Please answer f

Solution

as you can see it is a 2 tailed test because the alternative hypothesis is equal not

alpha / 2 = 0.05 / 2 = 0.025

df = 25-1= 24

critical value : 2.064

values of thetha^ would lead you to reject the null hypothesis : greater than critical value than in this case will be greater than 2.064
