Answer #1

A medical school claims that more than 28% of its students plan to go into general practice.

Sample size = n = 130

Sample proprotion = = 0.39

x = n* = 130*0.39 = 50.7 51

By using TI-84 calculator we have to find p-value.

Click on STAT ------>TESTS ------->1-PropZTest------> Enter values ---->

P0: 0.28

x: 51

n: 130

prop > p0

Calculate

We get P-value = 0.0022

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 3-4.00 in GPA. They then take a random sample of 200 of their graduates at the state college and find...

A principal claims the students in his school have above-average test scores for a particular standardized test. A sample of 50 students from his school were found to have an average test score of 77.2. The population mean for test scores for this particular test is 75, with a standard deviation of 9 (so we can assume that the population test score is normally distributed). Set up a hypothesis test to determine whether this principal’s claim is correct (use alpha...
