A random sample of adult drivers was obtained, 53% men and 46% women. A survey showed that 57% of the drivers rely on GPS systems. 32% of the drivers are men and use GPS while 24% of the drivers are women and use GPS. Suppose a person included in this survey is randomly selected. a.) Suppose the person selected is a man. What is the probability that he relies on a GPS system? Your answer should have at least 3...

A random sample of 88 women showed that the mean number of children reported was 1.58 with a standard deviation of 1.8. (interestingly, a sample of 88 men showed a mean of 1.3 children.) Complete parts (a) through (c) below EEB Click the lcon to view the ttable. Find a 95% confidence interval for the population mean number of children for women. Because the sample size is so large, you can use 1.96 for the critical value of t (which...
