Question Answered step-by-step Approximately 21% of U.S. residents ages 5 and older speak a… Approximately 21% of U.S. residents ages 5 and older speak a language other than English at home (source (Links to an external site.)). 790 people are randomly selected from the population. Considering “speaks a language other than English at home” to be a success, answer the following:a: What is the mean number of people in a sample this size who speak a language other than English at home? (Round to the nearest whole person as needed.) b: Which of the following notations represents the probability that at most 159 of these people speak a language other than English at home? (Enter the number for your answer.)1. P(X<159)2. P(159)3. P(X?159)4. P(X>159) c: Which of the following commands would you enter in Sheets/Excel to calculate the probability that at most 159 of these people speak a language other than English at home? (Enter the number for your answer.)1. 1-BINOM.DIST(159, 790, 21, false)2. BINOM.DIST(790, 0.159, 0.21, true)3. BINOM.DIST(0.159, 790, 0.21, false)4. BINOM.DIST(159, 790, 0.21, true) (Round all following answers to 3 decimal places.)d: Calculate it: What is the probability that at most 159 of these people speak a language other than English at home? e: What is the probability that exactly 171 of these people speak a language other than English at home? f: What is the probability that at least 148 of these people speak a language other than English at home?
