Step-by-Step Solution:

Step 1 of 5) For Problems 1 and 2, (a) determine the null and alternative hypotheses, (b) explain what it would mean to make a Type I error, (c) explain what it would mean to make a Type II error, (d) state the conclusion that would be reached if the null hypothesis is not rejected, and (e) state the conclusion that would be reached if the null hypothesis is rejected. 2. More Credit-Card Debt Among all credit cards issued, the proportion of cards that result in default was 0.13 in 2010. A credit analyst with Visa believes this proportion is different today. Figure 30 shows the bar graph of the conditional distribution in Table 15. The blue bars represent the proportion of men admitted for each program; the green bars represent the proportion of women admitted for each program. Four of the six programs actually had a higher proportion of women accepted! And the proportion of men accepted in programs C and E is not much higher than the proportion of women. What caused the overall proportion of accepted men to be so much higher than the overall proportion of accepted women within the entire university, when, within each program, the proportions differ very little and may imply that women are accepted at a higher rate The initial analysis did not account for the lurking variable, program of study. There were many more male applicants in programs A and B than female applicants, and these two programs happen to have higher acceptance rates. The higher acceptance rates in these programs led to the false conclusion that the University of California, Berkeley, was biased against ge
