An unknown distribution has a mean of 98 and a standard deviation of 13. Samples of size n = 64 are drawn randomly from the population. Check off the following that are true. At least one must be true. On ≥ 30 Complete the following table for the distribution of X and X. Round the standard deviation of X (standard error of the mean) to four decimal places as needed. X Sample size Standard deviation Distribution P(96 < X < 100) Mean = OX is normally distributed 94.74 98 13 Unknown a. Find the probability that a randomly selected sample mean is between 96 and 100. Use Geogebra to find the each of the following probabilities. X Select an answer V 96.37 98 99.63 96 X 100 X X Round your answer to four decimal places 101 26 102. Q b. Find the value that is two standard deviations above the expected value of the sample mean. Round your answer to one decimal place as needed Hint: +2 x ox
