Question
According to a recent report, 46% of college student internships are unpaid. A recent survey of 100 college interns at a local university found that 58 had unpaid internships.
a. Use the five-step p-value approach to hypothesis testing and a 0.05 level of significance to determine whether the proportion of college interns that had unpaid internships is different from 0.46.
b. Assume that the study found that 49 of the 100 college interns had unpaid internships and repeat (a). Are the conclusions the same?
Let π be the population proportion. Determine the null hypothesis, H0, and the alternative hypothesis, H1.
H0: P__
H1: P__

- Among college students, the proportion p who say they're interested in their congressional district's election results has traditionally been 75%. After a series of debates on campuses, a political scientist claims that the proportion of college students who say they're interested in their district's election results is more than 75%. A poll is commissioned, and 217 out of a random sample of 265 college students say they're interested in their district's election results. Is there enough evidence to support the political scientist's claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H₁.

- It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus. In a random sample of 120 students of its 12124 students, 15 were left-handed. Does this provide enough evidence to show that students at this college have a higher percentage of left-handers than the general American population? Use a 10% level of significance.arrow_forwardIf Miller (2008) wanted to know if males consume significantly more energy drinks than the overall population average, which of the following are the correct hypotheses?arrow_forwardA medical school claims that more than 28% of its students plan to go into general practice.
