: I was wondering if anyone can help me with these. I'm having issues with understanding how they are suppose to go and be worked. The third * I have how I think it should be set up but still don't know how to go any further. Any help is greatly appreciated. Thank you.
*The pulse rates below were recorded over a 30-second time period, both before and after a physical fitness regimen. The data is shown below for 8 randomly selected participants. Is there sufficient evidence to conclude that a significant amount of improvement took place? Assume pulse rates are normally distributed. Test using  = 0.05.
Before 31 25 30 31 33 25 32 45
After 32 29 30 37 40 35 34 52

* A teacher wishes to compare two different groups of students with respect to their mean time to complete a standardized test. The time required is determined for each group. The data summary is given below. Test the claim at = 0.05, that there is no difference in variance. Give the critical region, test statistic value, and conclusion for the F test.
n1=60, s1=24
n2=120, s2=28
= 0.05


*Determine the p-value for each of the following hypothesis-testing situations:
a. H0: p = 0.30 and Ha: p  0.30; z test value = 1.65
p(z>1.65) = , p(z<-1.65=
b. H0:   30 and Ha:  < 30; t test value = - 1.7 d.f. = 15
p(t<-1.7)=
