.A sample of 30 student athletes were selected from of a student population with an average score of 78 on trait level aggression. After a short survey, the student athlete sample scored M = 90 with s = 7. Find the appropriate statistic and compare to the critical value. Assume a one-tailed test with α = .01. State the whether to reject or fail to reject the null hypothesis.
Bonus: Why would the researcher choose the above assumptions?

Bonus: Why would the researcher choose the above assumptions?
n= 30,, x= 90, s= 7
Test Hypothesis:
Test statistic-
P -value <0.01 Reject
This is no sufficient evidence to claim the data.
