Answer:
H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0
Explanation:
Null hypothesis would be there not being a difference, so the difference would be 0.
Alternative hypothesis would be that there is a difference. However, the president of the university does not want to determine whether more males than females, or more females than males, get a GPA of 3.5 or higher, so the alternative hypothesis is =/= 0.
According to the result of the test statistic, the p-values are given by:
a) 0.0352.
b) 0.9648.
c) 0.0704.
<h3>How to find the p-value of a test?</h3>
It depends on the test statistic z, as follows.
- For a left-tailed test, it is the area under the normal curve to the left of z, which is the <u>p-value of z</u>.
- For a right-tailed test, it is the area under the normal curve to the right of z, which is <u>1 subtracted by the p-value of z.</u>
- For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is <u>2 multiplied by 1 subtracted by the p-value of z.</u>
In this problem, the test statistic is z = 1.8, which has a p-value of 0.9648.
Item a:
Right-tailed test, hence the p-value is of 1 - 0.9648 = 0.0352.
Item b:
Left-tailed test, hence the p-value is of 0.9648.
Item c:
Two-tailed test, hence the p-value is of 2 x (1 - 0.9648) = 2 x 0.0352 = 0.0704.
