A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the school's students, 39% of them plan to go into general practice. Find the P-value for a test of the school's claim.
How do I do this in a TI-84?
Homework Answers
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

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
