(a) Obtain the probability that exactly 28 of them are home owners. The probability that exactly 28 of them are home owners is obtained below as follows: Let X denotes the number of Americans are home owners which follows binomial distribution with the probability of success 0.64 with the number of people randomly selected is 42. The required probability is, Use Excel to obtain the probability value for x equals 28. Follow the instruction to obtain the P-value: Open EXCEL Go to Formula bar. In formula bar enter the function as“=BINOMDIST” Enter the number of success as 28. Enter the Trails as 42. Enter the probability as 0.64. Enter the cumulative as False. Click enter. EXCEL output: From the Excel output, the P-value is 0.1215. The probability that exactly 28 of them are home owners is 0.1215. (b) Obtain the probability that at most 26 them are home owners. The probability that at most 26 them are home owners is obtained below as follows: The required probability is, Use Excel to obtain the probability value for x equals 26. Follow the instruction to obtain the P-value: Open EXCEL Go to Formula bar. In formula bar enter the function as“=BINOMDIST” Enter the number of success as 26. Enter the Trails as 42. Enter the probability as 0.64. Enter the cumulative as True. Click enter. EXCEL output: From the Excel output, the P-value is 0.4456. The probability that at most 26 them are home owners is 0.4456. (c ) Obtain the probability that at least 25 them are home owners. The probability that at least 25 of them are home owners is obtained below as follows: The required probability is, Use Excel to obtain the probability value for x equals 24. Follow the instruction to obtain the P-value: Open EXCEL Go to Formula bar. In formula bar enter the function as“=BINOMDIST” Enter the number of success as 24. Enter the Trails as 42. Enter the probability as 0.64. Enter the cumulative as True. Click enter. EXCEL output: From the Excel output, the P-value is 0.2204. The probability that at least 25 of them are home owners is 0.2204.
