Below, n is the sample size, p is the population proportion of successes, and X is the number of successes in the sample. Use the normal approximation and the Cumulative Normal Distribution Table to find the probability. Round the answer to at least four decimal places. n=76, p=0.41 P(28 < X<38) = X a E >

Use the standard normal table to find the​ z-score that corresponds to the given percentile. If the area is not in the​ table, use the entry closest to the area. If the area is halfway between two​ entries, use the​ z-score halfway between the corresponding​ z-scores. If​ convenient, use technology to find the​ z-score. P18 The​ z-score that corresponds to P18 is

Find the margin of error for the given values of c, s, and n. c=0.90, s = 3.5, n = 6 Click the icon to view the t-distribution table. The margin of error is (Round to three decimal places as needed.)

Find the probability for a normal distribution p(-0.80

What percent of the total population is found between the mean and the z-score given? (Use the standard normal distribution table and enter your answer to two decimal places.) z = 3.42

Find the margin of error for the given values of c, s, and n. c = 0.99, s = 3.1, n = 27 Click the icon to view the t-distribution table. The margin of error is (Round to one decimal place as needed.)
