Consider sample data with x bar = 10 and s = 2. (For each answer, enter an exact number.) (a) Compute the coefficient of variation (as a percent). % (b) Compute a 75% Chebyshev interval around the sample mean. Lower Limit Upper Limit
Consider the mean of a random sample of size 75, X¯. If S 2 is the sample variance and the population is normally distributed with mean µ, what is the distribution of X¯ − µ S/√ 75
Let X be the mean of a random sample of size n = 75 from the uniform distribution on the interval (0,4), .e 0, otherwise. Approximate the probability P(1.84 < X 〈 2.16).
Let X be the mean of a random sample of size n = 75 from the uniform distribution on the interval (0,4), .e 0, otherwise. Approximate the probability P(1.84 < X 〈 2.16).
21. Calculate the 95% Confidence interval around a sample mean of 100, based on a sample NE 25 with a (population standard deviation) o = 10. (4 points)
9. Consider the mean of a random sample of size 75, X. If S2 is the sample variance and the population is normally distributed with mean y, what is the distribution of 10. The mean weight of peanuts in a sample of size 16 from a barrel is 0.09 ounces. The standard deviation of the sample is 0.015 ounces. What is a 90% confidence interval for the mean weight of all peanuts in the barrel? Assume peanut weights in the...
