Suppose that we will randomly select a sample of 64 measurements from a population having a mean equal to 20 and a standard deviation equal to 4. (a) Describe the shape of the sampling distribution of the sample meanx. Do we need to make any assumptions about the shape of the population? Why or why not? Normally distril v no v . because the sample size is large (b) Find the mean and the standard deviation of the sampling distribution of the sample mean X. (Round your og answer to 1 decimal place.) (c) Calculate the probability that we will obtain a sample mean greater than 21; that is calculate Rx > 21). Hint: Find the zvalue corresponding to 21 by using u; and o; because we wish to calculate a probability about X. (Use the rounded standard error to compute the rounded Z-score used to find the probability. Round your answer to 4 decimal places. Round z-scores to 2 decimal places.) PLE> 21) (d) Calculate the probability that we will obtain a sample mean less than 19.385, that is, calculate P <19.385) (Use the rounded standard error to compute the rounded Z-score used to find the probability. Round your answer to 4 decimal places. Round z-scores to 2 decimal places.) Pl <19.385)
