Question 1131234: A company that produces 8 oz. Low fat yogurt cups wanted to estimate the mean number of calories for us cups. A random sample of 10 such cups produced the following calories 147, 159, 153, 146, 144, 161, 163, 153, 143, 158
Construct a 99% interval for population mean. Assume number of Calories per such cup follow normal distribution

mean is 152.7
sd is 7.38 units calories
99%CI half-interval is t(0.995, df=9)*sigma/sqrt(10)
t is 3.25
half-interval is 3.25*7.38/sqrt(10)=7.58
99% interval is 152.7+/-7.6
(145.1, 160.3)
