Homework Answers
Answer #1
Claim: More than 28% of its students plan to go into general practice.
The null and alternative hypothesis is
H0: P = 0.28
H1: P > 0.28
Level of significance = 0.05
Sample size = n = 130
x = 51
Test statistic is
P-value = P(Z > 2.85) = 1 - P(Z < 2.85) = 1 - 0.9978 = 0.0022
P-value < 0.05 we reject null hypothesis.
Conclusion: More than 28% of its students plan to go into general practice.

Professor Jennings claims that only 35% of the students at Flora
College work while attending school. Dean Renata thinks that the
professor has underestimated the number of students with part-time
or full-time jobs. A random sample of 80 students shows that 38
have jobs. Do the data indicate that more than 35% of the students
have jobs? Use a 5% level of significance.

A college prep school advertises that their students are more
prepared to succeed in college than other schools. To verify this,
they categorize GPA’s into 4 groups and look up the proportion of
students at a state college in each category. They find that 7%
have a 0-0.99, 21% have a 1-1.99, 37% have a 2-2.99, and 35% have a
