A biologist studies the gestation period of wolves. Past data reveals that such gestation periods have a mean of 65 days with standard deviation 20 days. The normal distribution for the population is shown by the dotted black line. The biologist plans to take a random sample of 15 such wolves and will calculate the mean gestation period of the sample to compare to the known gestation periods. Compute the mean and standard deviation of the sampling distribution of sample means for a sample of size 15. Round your answers to the nearest tenth.
