Use both the classical and
P
-value approaches to test at the 5% level of
significance.
Solution:
Let
be equal to the population average of the amount of
money spent at the beginning of the semester by female students. Let
be
equal to the population average of the amount of money spent at the
beginning of the semester by male students.
Since the distributions for both groups of the amount of money spent at the
beginning of the semester are assumed to be normally distributed and both
sample sizes are greater than (>) 30, then we can apply the large sample
-test.
