Question 21, Multiple choice below. 21. The financial aid director of a large college reports that 38% of the students enrolled are receiving some sort of financial aid. A researcher claims the percentage is lower and finds (from sampling) 29 out of 116 students are receiving some sort of financial aid. At alpha = 0.05, decide whether the financial aid director's report that 38% of the students are receiving some sort of financial aid holds up. For question #21 (multiple choice), choose the alternative hypothesis. For #22, fill in the space provided with your calculated value for p hat. For question #23, fill in the space provided with your calculated z-value from the information provided. For #24, answer True or False with regard to rejecting the null hypothesis.

Section 6.3: Distribution of Differences in Proportions Example 1: Proportion of Foreign-Born Residents, Alabama and Arizona From the 2010 US Census, we learn that 13.9% of the residents of Arizona were born outside the US while 3.4% of the residents of Alabama were born outside the US. If we take random samples of 200 residents from each state and calculate the difference in the proportion of foreign-born residents (Arizona – Alabama), describe the shape, mean, and standard error of the distribution of differences in proportions.
