When 440 junior  college students were surveyed , 200 said they have a passport. Construct a 95 % confidence interval for the proportion of junior college students that have a passport. Assume the junior college enrolled 30,000 students. Round to the nearest thousandth. A]Compute the value of p(^) over the p. B]Determine the np(1-p)>to equal to 10 and n< equals 0.05 N C] Find the lower and upper bound of the confidence interval D]Interpret the confidence interval

A researcher was interested in comparing weekly salaries between men and women. Independent samples were drawn to find the average salary for each group. A 90% confidence interval for the difference between female and male employees was determined to be (-$110, $10) in a given week. Interpret the confidence interval Zero is contained in the interval so the probability that male employees earn the same as females is 0.9. 90% of the time, women earn less than men. ore per ek Based on these data, we would assume that female employees average between $110 and $10 than male employees O We are 90% confident that men earn between $110 less or $10 more than women in a given week.

It is not taking (0.1404, 0.3596) as the confidence interval
