The caloric consumption of 37 adults was measured and found to average 2 comma 199. Assume the population standard deviation is 259 calories per day.

Construct confidence intervals to estimate the mean number of calories consumed per day for the population with the confidence levels shown below.

a. 91 % b. 96 % c. 97 %

a. The 91 % confidence interval has a lower limit of nothing and an upper limit of ____. ​(Round to one decimal place as​ needed.)

b. The 96 % confidence interval has a lower limit of nothing and an upper limit of _____. ​(Round to one decimal place as​ needed.)

c. The 97 % confidence interval has a lower limit of nothing and an upper limit of _____. ​(Round to one decimal place as​ needed.)
