just question 18 please For #10 - 19: A researcher conducts an Independent-Measures study examining the effectiveness of a groupexercise program on muscle strength at an assisted living facility for elderly adults. One group of residents isselected to participate in the new weight training program and a second group participates in a fitness walkinggroup. After 8 weeks, the researcher records a strength score for each individual. The data are as follows:StrengthWalkingHere are some formulas and values to help:Pooled Variance (s?,) = 14GroupGroupn = 14n = 282S(M,-M2)n2M1 = 15M2 = 12t = M1 - M2 / S (M1-M2)10. In statistical notion, what is your null hypothesis?H1 = µ211. Calculate your estimated standard error (SM1 - M2).1.224712. Calculate your t-statistic. Compute it with the information and formulas which are given above.2.44913. How many df do you have?4014. Using two tails, an alpha level of .05 and the df you calculated above in #13, what is your tcritical?(Hint: If you have an in-between value on the Table of Values, just use the next largest df value-beneath where itwould have been found in the table.+2.701215. Do the t-test. What is your conclusion? Do you reject the null hypothesis or fail to reject the null hypothesis?There is enough evidence to conclude that there is significant difference between the population meanstrength scores for the residents who are reselected to weight training program and fitness walking, at 5% level ofsignificance. The exercise program of muscle strength is significantly effective. Reject the null hypothesis.16. What if there was a smaller difference between the two groups? That is, if M1 = 14 and M2 = 12. Then, what isyour t-statistic?1.63318.Cohen's d? Calculate it using M1 = 15 and M2 = 12estimated mean differenceM,-M,estimated d =estimated standard deviation

Question

Accepted Answer

Given that 
Sample sizes n1=14 , n2=28
M1=15 , M2=12
SP2=14

18.Cohen's d? Calculate it using M1 = 15 and M2 = 12 estimated mean difference M, -M, estimated d = estimated standard deviation
