You want to estimate the mean hourly yield for a process that manufactures an antibiotic. You observe the process for 100 hourly periods chosen at random, with the results of 32 ounces per hour and a standard deviation of 7 ounces. Calculate the 95% margin of error (in ounces per hour). (Round your answers to three decimal places.)

Answers

Answer:

The margin of error for the 95% confidence interval is of 1.389 ounces per hour.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 100 - 1 = 99

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.9842

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

Then

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

[tex]M = 1.9842\frac{7}{\sqrt{100}}[/tex]

[tex]M = 1.389[/tex]

The margin of error for the 95% confidence interval is of 1.389 ounces per hour.

1.) The function g is related to one of the parent functions

The parent function fis:
f(x)= x^2
Use function notation to write g in terms of f.​

Answers

Answer:

g is terms of f is given by: [tex]g(x) = f(x) + 6[/tex]

Step-by-step explanation:

We are given these following function:

[tex]g(x) = x^2 + 6[/tex]

And

[tex]f(x) = x^2[/tex]

Use function notation to write g in terms of f.​

We can see that function g(x) is f(x) added by 6. So

[tex]g(x) = f(x) + 6[/tex]

g is terms of f is given by: [tex]g(x) = f(x) + 6[/tex]

Jasmine conducted a survey of 83 people. 17/of them chose fish as their favorite dinner. How many would you expect to
choose fish out of the population of 250 people?

Answers

Answer:

52

Step-by-step explanation:

Ok, so first, we should find the fraction and turn that into a decimal. Do this by dividing the numerator by the denominator.

17/83 = 0.2048192771.

Now, we simply multiply our decimal by the new amount of people.

0.2048192771 x 250 = 51.2048192771.

Lastly, we should round our number up, as you can't possibly have a fraction of a person.

Our final answer is that roughly 52 people will be choosing fish, according to this sample

A shipping company charges an oversize package fee if the sum of the
dimensions of the package are more than 60 in. The length of the package you
want to send must be twice its width. What are the dimensions of a package
with maximum volume that avoids the oversize fee?​

Answers

Answer: Length = 40 inches

Width = 20 inches

Step-by-step explanation:

Let the width of the package be represented by x.

Since the length of the package must be twice its width, therefore the length will be: = 2 × x = 2x

Since the sum of the dimensions equals 60 inches. This will then be:

x + 2x = 60.

3x = 60

x = 60/3

x = 20

Therefore, the width = 20 inches

Length = 2x = 2 × 20 = 40 inches

The dimensions should be 40 by 20 inches.

which expression can you substitute for x in 5x+y=8 to solve the system below?
5x+y=8
x+4y=2

Answers

Answer:

x =30/19 and y =2/19

Step-by-step explanation:

5x + y = 8

x + 4y = 2

then

5x + y = 8

-5(x +4y =2)

5x + y = 8

-5x - 20y = - 10

0 +y - 20y = -2

- 19y = -2

y = 2/19 then

5x + 2/19 = 8

5x = 152-2/19

5x/5 =150/19 *1/5

x =30/19

Exterior angle property : It states that exterior angle is the sum of two opposite interior angles

y = 120 + 20 = 140°

Answer:

140 degrees

Step-by-step explanation:

A triangle's sum of interior angles is 180.

120+20=140

180-140=40

So X= 40.

X and Y are supplementary, so they both add up to 180.

180-40=140

Therefore, Y=140.

$59.95 and is on sale for 30% off. (3 points) help pls

Answers

Answer:

41.96$

Step-by-step explanation:

To find the discounted price we need to calculate the 30% of the $59.95

and to do that we need to multply 59.95 with 30 and divide it by 100

59.95 x 30 ÷ 100 = 17.985

59.95 - 17.985 = 41.965 and 41.96 is the discounted price

A local brewery distributes beer in bottles labeled 24 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 23.7 ounces and sample standard deviation of 0.8 ounces. . Test the claim by the government agency that the population mean is less than 24 ounces at the 0.01 level of significance.

Answers

Answer:

We reject H₀ . We support the feeling of people from a government agency

Step-by-step explanation:

Population information:

Population mean   μ  =  24 ou

Sample information:

Sample size   n  =  50    then   degree of fredom df = n - 1 = 49

Sample mean   x  = 23,7

Sample standard deviation   s = 0,8

Hypothesis Test:

Null Hypothesis                          H₀                x  = μ

Alternative hypothesis              Hₐ                 x < μ

Significance level   α  = 0,01

We can conclude from the alternative hypothesis that we should develop a one tail-test ( to the left " if a local brewery is cheating its customers that mean,  they are selling less beer than they are supposed to)

With α  = 0,01 and df  =  49 we get from t-student table t(c) = - 2,4

To calculate t(s)

t(s) =  (  x  -  μ  ) / s/√n

t(s)  = ( 23,7  - 24  ) / 0,8/√50

t(s)  =  - 0,3* 7,07 / 0,8

t(s)  = - 2,12 / 0,8

t(s) = - 2,65

Comparing t(c) and t(s)

|t(c)| < |t(s)|

2,4 < 2,65

Then t(s) is in the rejection region we reject H₀ , and agree with a government agency in the fact that at 99 % of confidence interval shows that local brewery is cheating customers
