Consider the following. A Iandom sample of size n = 25 is selected from a normal population with mean ,u = 105 and standard deviation 0 = 13. Describe the shape of the sampling distribution of the sample mean. O The distribution is skewed right. O The distribution is approximately uniform. O The distribution is exactly normal. O The distribution is skewed left. 0 The distribution is approximately normal. Find the mean and standard error of the sampling distribution of the sample mean. mean E Random samples of size n were selected from a normal population with the means and variances given here. n=54,p= 3.02:9 Describe the shape of the sampling distribution of the sample mean. 0 The distribution is normal. 0 The distribution is skewed right. 0 The distribution is uniform. O The distribution is skewed left. 0 The distribution is bimodal. Find the mean and standard error of the sampling distribution of the sample mean. mean E Random samples of size n were selected from a normal population with the means and variances given here. _ _ 2 _ n 12,;1 114,5 _1 Describe the shape of the sampling distribution of the sample mean. 0 The distribution is bimodal.
