Use the following information to answer the questions:
The hypothesis testing H0: μ = 100 vs. Ha: μ ≠ 100. Random sample = 25 was collected and the mean was 90, and the sample standard deviation of 23. The population standard deviation is known and equal to 25.
I have to answer whether it's a one tail or two tail test, find the z score, the critical value at 5%, and the p value and then determine whether we reject or accept the test
Help pls
