Question

The amounts of time employees at a large İfthe sample size isn#22, find the mean and standard deviation of the distribution of sample means. The mean of the distribution of sample means is(Type an integer or a decimal.) The standard deviation of the distribution of sample means is work each day are normally distributed, with a mean of 7.5 hours and a standard deviation of 0.32 hour. Random samples of size 22 and 35 are drawn from he (Round to two decimal places as needed.) If the sample size is n 35, find the mean and standard deviation of the distribution of sample means The mean of the distribution of sample meansType an integer or a decimal) The standard deviation of the distribution of sample means is (Type an integer or decimal rounded to the nearest hundredth as needed.) What happens to the mean and the standard deviation of the distribution of sample means as the size of the O A. The mean stays the same, but the standard deviation decreases. O B. The mean and the standard devaton both decrease. sariple increases? Choose the corect answer below O C. The mean stays the same, but the standard deviation increases. O D.
