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 70 of the 120 college interns had unpaid internships and repeat​ (a). Are the conclusions the same?

Assume that the study found that 70 of the 120 college interns had unpaid internships and repeat​ (a). What is the test​ statistic?

ZStat=___

p-value=____

What is the final​ conclusion?

The result is __A__ part (a). __B__ the null hypothesis. There __C__ sufficient evidence that the proportion of college interns that had unpaid internships is __D__ 0.46 because the p-value __E__ the level of significance.
