c) If you take a sample of size 42, can you say what the shape of the distribution of the sample mean is? ? Why or why not? On is less than 30 U population is normal Do is known O o is unknown On is at least 30 population is not normal d) For a sample of size 42, state the mean and the standard deviation of the sampling distribution of the sample mean. mean of the sampling distribution of the sample meanwhen n = 42: standard deviation of the sampling distribution of the sample mean when n = 42 rounded to two decimal places: Check AnswerA random variable X is not normally distributed. It has a mean of 38 and a standard deviation of 5. List the givens with correct symbols: ? = 38 7 v =5 a) If you take a sample of size 11, can you say what the shape of the sampling distribution for the sample mean is? Why or why not? Check all that apply. Do is known On is less than 30 O population is not normal On is at least 30 Oo is unknown O population is normal b) For a sample of size 11, state the mean and the standard deviation of the sampling distribution of the sample mean. mean of the sampling distribution of the sample mean when n = 11: standard deviation of the sampling distribution of the sample mean when n = 11 rounded to two decimal places: c) If you take a sample of size 42, can you say what the shape of the distribution of the sample mean is? ?
