Step-by-step explanation:

n 1990, the mean height of women 20 years of age or older was 63.7 inches based on data obtained from theCDC. Suppose that a random sample of 45 women who are 20 years of age or older in 2015 results in a meanheight of 63.9 inches with a standard deviation of 0.5 inch. Does your sample provide sufficient evidencethat women today are taller than in 1990

Answers

Answer:

The sample does not provide sufficient evidence that women today are taller than women in 1990.

The difference in mean height is not significant to arrive at such a conclusion.

Step-by-step explanation:

Mean height of women 20 year of age or older in 1990 = 63.7 inches

Mean height of women 20 years of age or older in 2015 = 63.9 inches

The standard deviation of the mean height in 2015 = 0.5 inch

The difference between the two years' mean height is 0.2 (63.9 - 63.7) inch.

This difference is less than the standard deviation of the mean height in 2015.

Therefore, the difference does not provide sufficient evidence that women today are taller than women in 1990.

Step-by-step explanation:

A machine that is programmed to package 1.20 pounds of cereal is being tested for its accuracy In a sample of 36 cereal boxes, the sample mean filling weight is calculated as 1.22 pounds. The population standard deviation is known to be 0.06 pound. Identify the relevant parameter of interest for these quantitative data. The parameter of interest is the proportion filling weight for all cereal packages. The parameter of interest is the average filling weight for all cereal packages.
A-1. Identify the relevant parameter of interest for these quantitative data.
A) The parameter of interest is the average filling weight of all cereal packages.
B) The parameter of interest is the proportion filling weight of all cereal packages.
A-2. Compute its point estimate as well as the margin of error with 95% confidence. (Round intermediate calculations to 4 decimal places.
B-1. Calculate the 95% confidence interval.
B-2. Can we conclude that the packaging machine is operating improperly?
A) Yes, since the confidence interval contains the target filling weight of 1.20.
B) Yes, since the confidence interval does not contain the target filling weight of 1.20.
C) No, since the confidence interval contains the target filling weight of 1.20.
D) No, since the confidence interval does not contain the target filling weight of 1.20.
C. How large a sample must we take if we want the margin of error to be at most 0.01 pound with 95% confidence?

Answers

Answer:

A) The parameter of interest is the average filling weight of all cereal packages. ;

Point estimate = 1.22

Margin of Error = 0.0196

Confidence interval = (1.2004, 1.2396)

C) No, since the confidence interval contains the target filling weight of 1.20.

Step-by-step explanation:

A) The parameter of interest is the average filling weight of all cereal packages.

The point estimate = sample mean = 1.22

The margin of error with 95% confidence :

Zcritical * σ/sqrt(n)

Zcritical at 95% confidence = 1.96

Margin of Error = 1.96 * 0.06/sqrt(36)

Margin of Error : 1.96 * 0.01

Margin of Error = 0.0196

Confidence interval :

xbar ± margin of error

1.22 ± 0.0196

Lower boundary = 1.22 - 0.0196 = 1.2004

Upper boundary = 1.22 + 0.0196 = 1.2396

(1.2004, 1.2396)

C) No, since the confidence interval contains the target filling weight of 1.20.

Since, the internal contains 1.20, then we can conclude that it is filling properly.

Clarissa wants to create more shade in her yard to block the hot sun, so she buys a sapling of an oak tree and plants it in the yard. To make sure the tree is growing at a healthy rate, she makes the following table to track its height over a period of weeks. What is the average rate of change in the tree's height from week 3 to week 9? Enter your solution into the box below.

Answers

Answer:

The answer is 7.

Step-by-step explanation:

Determine what values to use from the table to find the average rate of change.  

The problem asks for the average rate of change (AROC) from week 3 to week 9. The points referring to these measurements would be (3, 41) and (9, 83), respectively.

Step 2

FInd the AROC from (3, 41) to (9, 83).

The formula for the slope of a line between two given points (which is the same as AROC from the first two the second point) is

AROC  = y2−y1x2−x1

In your points, x1 is 3, x2 is 9, y1 is 41, and y2 is 83. Plug these values into the above formula and simplify.

AROC =  83−419−3=426=7  

The AROC is 7.

Step 3

Enter your solution.

Enter the value 7 and move on to the next question.

An investor decides to offer a business owner a $45,000 loan at simple interest of 3.5%
per year. Find the total amount in dollars, the investor will receive when the loan is
repaid after 7 years.

Answers

Answer:

A = $56025

Step-by-step explanation:

Given that,

An investor decides to offer a business owner a $45,000 loan at simple interest of 3.5%  per year.

Principal, P = 45,000

Rate of interest, R = 3.5%

We need to find the total amount the investor will receive when the loan is  repaid after 7 years.

The formula for the simple is given by :

[tex]I=\dfrac{PRT}{100}\\\\=\dfrac{45000\times 3.5\times 7}{100}\\\\=\$ 11025[/tex]

We know that,

Amount = Principal + simple interest

So,

A = 45,000 + 11025

A = $56025

So, the required amount is equal to $56025.

The shekel is fixed at 0.30 dollars per shekel. The countrys international reserves are $600. Foreign financial investors hold checking accounts in the country in the amount of 5,000 shekels.A. Suppose that foreign financial investors do not fear a devaluation of the shekel, and thus do not convert their shekel checking accounts into dollars.After one year, the value of the countrys international reserves is , which means that the country (doesn't want to / must not / can / cannot) maintain its fixed value of 0.30 U.S. dollars per shekel.B. Now suppose that foreign financial investors come to expect a possible devaluation of the shekel to 0.25 U.S. dollars.In regards to whether this possibility should worry them or not, which of the following statements is correct:multiple choice:a. This possibility should not worry them, as a depreciation of the shekel would mean that the shekel would suddenly become worth more in terms of other currencies.b. This possibility should not worry them, as the nation can always print additional shekels to avoid a depreciation of the shekel.c. This possibility should worry them, as a depreciation of the shekel would mean that the shekel would suddenly become worth less in terms of other currencies.d. This possibility should worry them, as a devaluation of the shekel to 0.25 U.S. dollars, would put the official value of the shekel below its fundamental or equilibrium value.C. In response to their concern about devaluation, foreign financial investors withdraw all funds from their checking accounts and attempt to convert those shekels into dollars.Converting all funds in the checking from shekels into dollars would require international reserves of $ , which means that the country (might be able to / can / cannot / doesn't want to) maintain its fixed value of 0.30 U.S. dollars per shekel for this year.D. Which of the following statements is correct in regards to whether the foreign investors forecast of devaluation can be considered a "self-fulfilling prophecy" or not:multiple choice:a. As the government purposefully set the official exchange rate to something other than the fundamental value, the actions of the government can be said to serve as a "self-fulfilling prophecy."b. Since official exchange rates are set and maintained by the government, the actions of international investors are of little concern and cannot be said to be a "self-fulfilling prophecy."c. Since fear of devaluation among the investors was enough to cause an actual devaluation, this can be considered a "self-fulfilling prophecy."d.
