For a statistics class project, a college student randomly samples 75 men who exercise at a gym regularly and 68 women who exerc

ise at a gym regularly. The college student believes that on average men spend more time at the gym each week. The college student records the number of minutes each person exercises in a given week. The college student conducts a hypothesis test at the 5% significance level. Use the summary statistics below to conduct a hypothesis test using your calculator or calculator

Answer:

Step-by-step explanation:

The record of the statistics and the summary statistics which are the missing files in the question are attached below.

From the given information:

The null hypothesis and the alternative hypothesis can be represented by :

\mathbf{H_o:} There is no difference between the average time  spend by men and women at gym each week

\mathbf{H_i:} The average time  spend by men is greater than the average time spend by women at the gym each week

From the summary statistics in the attached file below:

The p-value = 0.3253

Level of significance = 5% = 0.05

Therefore; it is obvious that the p-value is greater than the level of significance  i.e (0.3253 > 0.05)

Hence; there is no enough evidence to reject the null hypothesis

CONCLUSION: We conclude that the mean number of minutes exercised per week is larger for men than women at the  this gym.

Find the values of the apple, banana and lollypop below.<br><br> Pls help
maks197457 [2]

Answer:

a= Apple = 3

b= Banana =5

v= Lollypop=1

Step-by-step explanation:

36 is divided into 2 giving us 18

Let apple=a

Banana=b

Lollypop=c

In the first half

An apple + 3 bananas=18

a+3b=18 (1)

Second half is further divided into 2

That is,

18÷2=9

First half of the second half

3apples=9

3a=9 (2)

Second half of the second half

1 apple + 1 banana + 1 lollypop=9

a+b+c=9 (3)

a+3b=18 (1)

3a=9 (2)

a+b+c=9 (3)

From (2)

3a=9

Divide both sides by 3

a=9/3

a=3

Substitute a=3 into 1

a+3b=18

3+3b=18

3b=18-3

3b=15

Divide both sides by 3

b=15/3

=5

b=5

Substitute the value of a and b into (3)

a+b+c=9

3+5+c=9

8+c=9

c=9-8

c=1

Therefore,

a= Apple = 3

b= Banana =5

v= Lollypop=1

What are the types of roots of the equation below?<br><br>x^4 - 81 = 0​
natali 33 [55]

Answer:

x^4 - 81 = 0  

(x² - 9)(x² + 9) = 0  

Notice that the first of these is itself a difference of two squares:  

(x - 3)(x + 3)(x² + 9) = 0  

So the solutions are x = 3, x = -3, x = 3i, x = -3i

Triangle KJL is inscribed in semicircle O shown below such that JK=6 and JL=11. Which of the following is closest to the radius
lakkis [162]

Uhh, answer choices?

In any case, since \triangle KJL is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem, KL=\sqrt{6^2+11^2}=\sqrt{157}. Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so OJ=OK=OL=\frac{\sqrt{157}}{2}\approx \boxed{6.265}.

What would the graph of y=x look like? name three ordered pairs that lie on the line.
ololo11 [35]

-- The graph looks like a line that passes through the origin,
and slopes up to the right at a 45-degree angle.

-- Point #1 on the line:
. . . . . Pick any number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

-- Point #2 on the line:
. . . . . Pick any other number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

-- Point #3 on the line:
. . . . . Pick any other number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

Rinse and repeat, as many times as you like,
until the novelty wears off and you lose interest.
