30 people are selected randomly from a certain town. If their mean age is 60.5 and the population standard deviation of 4.6, find a 95% confidence interval for the true mean age of everyone in the town. O a. 58.86 to 62.14 O b. 58.28 to 62.72 O c. 58.85 to 62.15 O d. 59.42 to 61.58
Which interval is which? Matilda constructed three confidence intervals, all from the same random sample. The confidence levels are 95%, 98%, and 99.9%. The confidence intervals are I. 5.2 <µ<6.8 II. 5.5<µ<6.5 III. 5.4 <µ<6.6 Unfortunately, Matilda has forgotten which confidence interval has which level. Match each confidence interval with its level. 5.2 <µ<6.8 is the (Choose one) confidence interval. 95% 5.5
