Subjects in a study by Dabonneville et al. (A-9) included a sample of 40 men who claimed to engage in a variety of sports activities (multisport). The mean body mass index (BMI) for these men was 22.41 with a standard deviation of 1.27. A sample of 24 male rugby players had a mean BMI of 27.75 with a standard deviation of 2.64. Is there sufficient evidence for one to claim that, in general, rugby players have a higher BMI than the multisport men? Let a ¼ :01.

Answers

Answer:

The responses can be defined as follows:

Step-by-step explanation:

Given:

[tex]H_o : \mu_1 = \mu_2\\\\H_a : \mu_1 < \mu_2[/tex]

Testing the hypothesis:

[tex]Z=\frac{( \bar{x_1}-\bar{x_2})}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}}}[/tex]

   [tex]=\frac{(22.41-27.75)}{\sqrt{(\frac{1.27^2}{40}+\frac{2.64^2}{24})}}\\\\=-9.29\\\\[/tex]

[tex]a=0.01[/tex]

critical value [tex]Z(0.01)=-2.33[/tex] (using the standard normal table)

[tex]Z=-9.29<-2.33[/tex] so, we reject [tex]H_o[/tex].

Using the t-distribution, it is found that since the test statistic is greater than the critical value for the right-tailed test, there is sufficient evidence for one to claim that, in general, rugby players have a higher BMI than the multisport men.

At the null hypothesis, it is tested that rugby players do not have a higher BMI than the multi-sport men, that is, the subtraction of the means is not greater than 0, hence:

[tex]H_0: \mu_R - \mu_M \leq 0[/tex]

At the alternative hypothesis, it is tested if they have a higher BMI, that is:

[tex]H_1: \mu_R - \mu_M > 0[/tex]

We have the standard deviation for the samples, hence, the t-distribution is used.

The standard errors are given by:

[tex]s_M = \frac{1.27}{\sqrt{40}} = 0.2008[/tex]

[tex]s_R = \frac{2.64}{\sqrt{24}} = 0.5389[/tex]

For the distribution of differences, the mean and the standard error are given by:

[tex]\overline{x} = \mu_R - \mu_M = 27.75 - 22.41 = 5.34[/tex]

[tex]s = \sqrt{s_M^2 + s_R^2} = \sqrt{0.2008^2 + 0.5389^2} = 0.5751[/tex]

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Hence:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

[tex]t = \frac{5.34 - 0}{0.5751}[/tex]

[tex]t = 9.29[/tex]

Using a t-distribution calculator, for a right-tailed test, as we are testing if the mean is greater than a value, with a significance level of 0.05 and 40 + 24 - 2 = 62 df, the critical value is of [tex]t^{\ast} = 1.67[/tex]

Since the test statistic is greater than the critical value for the right-tailed test, there is sufficient evidence for one to claim that, in general, rugby players have a higher BMI than the multisport men.

Slope = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

So taking 2 points (0,0) and (60,120)

we have slope = (120-0)/(60-0) = 120/60 = 2

general equation of linear graph is y=mx+b with m be the slope

so y=2x+b

Now to find b, just plug any point of the graph in, such as (0,0)

so we get something like 0=2(0) + b => b=0

So your equation is y=2x

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amy:

Number of toys = 3x

Carly:

Number of toys = x

Now,

In total, they have 160 Star Wars toys.

So,

x + 3x = 160

4x = 160

x = 40

Now,

3x = 3 x 40 = 120

x = 40.

Thus,

Amy has 120 toys.

Carly has 40 toys.

a block of wood has a mass of 3.5 kilogram. the wood has density 0.065 kg/m3

work out the volume of the block of wood​

Answers

Step-by-step explanation:

Given :-

A block of wood has a mass of 3.5 kilogram. The wood has density 0.065 kg/m³.

And we need to find out the volume of the wood. Density , volume and mass are related as ,

Density :-

Mass per unit Volume .

[tex]\implies\rm Density =\dfrac{Mass}{Volume}[/tex]

Substitute the respective values :-

[tex]\implies\rm Density =\dfrac{Mass}{Volume}\\\\\rm\implies 0.065 kg/m^3=\dfrac{3.5kg}{V}\\\\\rm\implies Volume = \dfrac{3.5kg}{0.065 kg/m^3}\\\\\implies\boxed{\red{\rm Volume = 53.84 m^3}}[/tex]

Hence the volume is 53.84 .

If she earned $23,500 how many of each type of deck did she build?

Answers

if she build x numbers of large decks, therefore small decks would be (x + 5)

1500*(x+5)+2500x   =23500

1500x+7500+2500x=23500

A perpendicular bisector is defined as a line or a line segment that divides a given line segment into two parts of equal measurement. 'Bisect' is the term used to describe dividing equally. Perpendicular bisectors intersect the line segment that they bisect and make four angles of 90° each on both sides.

Here, AB⊥CD.

Since CD is the perpendicular bisector of AB.
