Provide an appropriate response. A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial assistance. Use a 95% confidence interval to estimate the true proportion of students on financial aid. Express the answer in the form

Provide an appropriate response.Find the critical t-value that corresponds to 90% confidence and n = 21. (Round to 3 decimal places)

Provide an appropriate response.The probability that a football game will go into overtime is 18%. In 140 randomly selected football games, what is the mean and the standard deviation of the number that went into overtime? Mean = [answer1]  Standard deviation = [asnwer2]   (Round your answer to two decimal places.)

Provide an appropriate response.In a recent survey, 72% of the community favored building a health center in their neighborhood. If 14 citizens are chosen, find the probability that exactly 8 of them favor the building of the health center. (Round to the nearest ten-thousandths.)

Provide an appropriate response.Assume that the heights of men are normally distributed with a mean of 69.7 inches and a standard deviation of 3.5 inches. If 100 men are randomly selected, find the probability that they have a mean height greater than 70.7 inches.
