T Distribution Table
The U.S. Dairy Industry wants to estimate the mean yearly milk consumption. A sample of 25 people reveals the mean yearly consumption to be 82 gallons with a standard deviation of 24 gallons. Assume that the population distribution is normal. (Use Distribution Table.) a-1. What is the value of the population mean? 82 24 Unknown a-2. What is the best estimate of this value? Estimate population mean c. For a 90% confidence interval, what is the value...

A random sample of 20 chocolate energy bars of a certain brand has, on average, 210 calories per bar, with a standard deviation of 15 calories. Construct a 99% confidence interval for the true mean calorie content of this brand of energy bar. Assume that the distribution of the calorie content is approximately normal.

(a) Is there a difference
in the measurement of the muzzle velocity between device A and
device B at the α = 0.01 level of significance? Note: A normal
probability plot and boxplot of the data indicate that the
differences are approximately normally distributed with no
outliers. Let di = Ai − Bi.
(i) Identify the null and alternative
hypotheses.
(ii) Determine the test statistic for
this hypothesis test (t0 = ?). Round to two
decimal places as needed.
