Homework Answers
a) The null and alternative hypothesis is Given as,
H0: 
=5 against H1:
>5
Clearly this is a one tail test.
Since, alternative hypothesis is of '>' type.
So, it is called more than type or a right tail test.
b) now it is given that
=5. But the null hypothesis is rejected.
So, it means null hypothesis is rejected when it is true.
Hence this is a type I error.

Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor would...
