Transcribed Image Text:According to a recent report, 45% of college student internships are unpaid. A recent survey of 80 college interns at a local university found that 46 had unpaid internships.
a. Use the five-step p-value approach to hypothesis testing and a 0.10 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.45.
b. Assume that the study found that 40 of the 80 college interns had unpaid internships and repeat (a). Are the conclusions the same?
a. Let a be the population proportion. Determine the null hypothesis, H,, and the alternative hypothesis, H,
Ho: 1
H,: 1
(Type integers or decimals. Do not round.)
What is the test statistic?
ZSTAT =D
(Round to two decimal places as needed.)
What is the p-value?
The p-value is
(Round to three decimal places as needed.)
What is the final conclusion?
V the null hypothesis. There
sufficient evidence that the proportion of college interns that had unpaid internships is
0.45 because the p-value is
V the level of significance.
b. Assume that the study found that 40 of the 80 college interns had unpaid internships and repeat (a). What is the test statistic?
ZSTAT =O
(Round to two decimal places as needed.)
What is the p-value?
The p-value is|
(Round to three decimal places as needed.)
What is the final conclusion?
The result is
V part (a)
v the null hypothesis. There
sufficient evidence that the proportion of college interns that had unpaid internships is
v 0.45 because the p-value is
v the level of significance.
