B. Find and interpret the mean, variance, and standard deviation of the sampling distribution of sample means. Round your answers to one decimal place. 1. The mean age of employees at a large corporation is 47.2 years with a standard deviation of 3.6 years. Random samples of size 36 are drawn from this population and the mean of each sample is determined. 2. In a sample of 900 gas stations, the mean price of regular gasoline at the pump was P54.04 per liter and the standard deviation is P0.42 per liter. From this population, a random sample is drawn of size: а. 30. b. 55.
