You take a random sample of 25 student athletes and measure their diastolic blood pressure. the sample mean is 70 (the units are mm hg) and the population variance = ď 2 (this will change in the parts of the question below). consider the null hypothesis that diastolic blood pressure is over 80mm hg versus the relevant alternative hypothesis (ha : ⵠ≤ 80). compute the p-value for each part below and state if you would reject the null at the î± = 4% level: a) ď 2 = 225 b) ď 2 = 900 4.1 using the information from # 4 a)â’b) above, calculate the p-value if the null hypothesis was that diastolic blood pressure equals 80mm hg versus the relevant alternative hypothesis (what is in each case, tell if you would you reject the null hypothesis at the î± = 4% level. a) b)

step-by-step explanation:

answer is  

c.

36

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
