A survey was done to determine who is more likely to ask for directions. A sample selected showed that 300 of 811 women would ask directions, while 255 of 750 men would ask directions. PART (1): The hypothesis is that women would be more likely to ask directions. Formulate the null and alternative hypothesis for this study. PART (2): What is the sample proportion of the women would ask directions? Sample proportion for men who would ask directions? What is the pooled estimate of p? PART (3): At alpha = .05, test the hypothesis. What is the conclusion?

The following is sample data of men and women who prefer blackjack. (Chart next page). Please show all math: PART (1): What is the point estimate of the proportion of women who prefer blackjack? PART (2): What is the point estimate of the proportion of men who prefer blackjack? PART (3): Construct a 95% confidence interval estimate of the difference between the proportion of men and women who favor blackjack.

Chart is as follows: Sample Size: Women = 320.....Men = 250 Favorite blackjack: Women = 256.....Men = 165
