The sample mean was given to be x = $253.45 spent per day and the sample standard deviation was given to be s = $75.50. The value of ta/2 was determined to be 1.998. All the values are now known to construct the confidence interval. S The lower bound of the confidence interval is calculated using the expression x-ta/2 √n Find this lower bound, rounding the result to two decimal places. lower bound = x-ta/2 = 253.45 1.998 Ei S upper bound = x + ta/2 √n The upper bound of the confidence interval is calculated using the expression x + ta/2 to two decimal places. 75.50 = 253.45 + 1.998 √64 75.50 √64 S √n Find this upper bound, rounding the result 74°F Sunny 4:18 PM 4/17/2023 Ę
