Significance level= 0.05
H0:u=11.5

Sample Size=49
Test statistic=-2.0064972
Two Tailed test:
Lower critical value= -2.0106
Upper Critical Value=2.0106
Lower Tailed test:
critical value=-1.6772242
p-value=0.02522735
Upper Tailed test:
critical value= 1.6882242
p-value= 0.97477265
I dont’ know which pieces of information to use, I have a feeling that all of the tailed test information isn’t necessary, but I don’t know. I would like to know the hypothesis for the scenario, the conclusion, the p-value (I think we were supposed to find it even though it was shown, if you understand and know if I am or not please let me know), and the conclusion. Please explain to me how to do all of this as well, if you can. I am soo confused. This is for a statistics class in college. I sadly

H1 is u not equal 11.5
this is a two tailed test
95% confidence table (consult t-score chart)
your test statistic, is inside the critical value, then you accept the claim.
the conclusion is, there is not sufficient evidence to warrwant the rejection of the null hypothesis
your p-value is 0.0505
the alpha is 0.025
