A random sample of n=100 observations is selected from a population with μ=29 and σ=24. Complete parts a through a.Find ​P(x≥​28)

Trap spacing measurements (in meters) for a sample of seven teams of red spiny lobster fisherman are reproduced in the accompanying table. Let u represent the average of the trap spacing measurements for the population of red spiny lobster fisherman. The mean and the standard deviation of the sample measurements are x = 91.4 meters and s = 12.2 meters, respectively. Suppose you want to determine if the true value of µ differs from 95 meters. Complete parts a through h below. μ 94 100 108 97 83 71 87 a. Specify the null and alternative hypotheses for this test. OA. Ho: μ = 95 Ha: μ 95 d. Find the approximate p-value of the test. OD.

We will obtain a sample of quarters and weigh them to determine the mean. How many quarters must we randomly select and weigh if we want to be 99% confident that the sample mean is within 0.025 grams of the true population mean for all quarters? Assume that σ = 0.2 grams
