Concept explainers

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

A sociologist wishes to conduct a poll to estimate the percentage of Americans who favor affirmative action programs for women and minorities for admission to college and universities. She wants to use a 2003 estimate of 55% obtained from a Gallup Youth Survey as a prior estimate. What sample size should be obtained if she wishes the estimate to be within 4 percentage points with 90% confidence?
According to the Pew Research Center, the proportion of the American population who use only a cellular telephone (no landline) is 0.37. Jason conducts a survey of thirty 20- to 24-year-olds who live on their own and finds that 16 do not have a landline to their home. Does this provide sufficient evidence to conclude that the proportion of 20- to 24-year-olds who live on their own and don’t have a landline is greater than 0.37? Use an a=0.10 level of significance.

Any basketball fan knows that Shaquille O'Neal, one of the NBA's most dominant centers of the last twenty years, always had difficulty shootinq free throws. Over the course of his career, his overall made free-throw percentaqe was 53.3%. Durinq one off-season, Shaq had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shag made 26 of 39 free-throw attempts. Test the claim that Shaq has significantly improved his free-throw shooting using a 0.05 significance level. . Check the conditions of the Central Limit Theorem for this scenario. What is the minimum number of free throws Shaq would have to attempt so that it would meet the condition of a large population size?
