A bulk food store sells 25-pound bags of potatoes. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely, so the distribution of weights is uniform. A sample of 100 bags is taken. What is the probability that the mean actual weight for the 100 bags of potatoes is less than 24.9?

A company packages a bulk product in bags with a 50-pound label weight. During a typical day's operation of the fill process, 22 subgroups of five bag fills are observed. Using the observed data, 1 and Rare calculated to be 52.9364 pounds and 1.6818 pounds, respectively. When the 22 I's and 22 Rs are plotted with respect to the appropriate control limits, the first 6 subgroups are found to be out of control. We found that the elimination of a...

A study measures blood pressure among college students. The lowest actual blood pressure is 70, and the highest is 130. Each blood pressure test is equally likely. It follows a uniform distribution. A sample of 100 students’ blood pressure is taken. (a) What is the probability that the mean of blood pressure is less than 97. (Round to 4 decimal places) (b) Find the 90 percentile for the mean of 100 blood pressure. (Round to 2 decimal places)

Potato weight in a local farm has a mean of 0.5 pound, and standard deviation of 0.15 pound. This year, the famer decided to pack 20 potatoes into a bag and label as 10 pounds. When the potatoes are sent to a grocery store, the store manager will randomly select a bag to see if it is underweight (less than 9.5 pounds).

Let x1, x2, . . . , x100 denote the actual net weights (in pounds) of 100 randomly selected bags of fertilizer. Suppose that the weight of a randomly selected bag has a distribution with mean 25 lb and variance 1 lb2. Let x be the sample mean weight (n = 100). (a) What is the probability that the sample mean is between 24.75 lb and 25.25 lb? (Round your answer to four decimal places.) P(24.75 ≤ x ≤ 25.25)...
