MTH final review 2,3,14

Thank you in advance!!!!!

QUESTION 2 Suppose we take a sample of size 15 and calculate the mean weight of the sample. The population weight is known to be skewed left. The shape of the sampling distribution of X is approximately normal O skewed right O skewed left O uniform O Not enough information to determineQUESTION 3 Given that the shape of the sampling distribution is approximately normal the standard deviation of sample means or standard error of the mean is O equal to the population standard deviation O the sample standard deviation calculated O the population standard deviation divided by sample size O the population standard deviation divided by the square root of sample size O1QUESTION 14 Suppose that the sampling distribution of a proportion, , has a standard deviation given by On. The quantity p(1 - p) is O Up OV Op O none of the above
