Study on how much time people spend with family in a day shows that the time spending distribution is approximately normally distributed with a mean of 86 minutes and a standard deviation of 32 minutes.
Q: Suppose a random sample of 20 people is obtained, describe the sampling distribution of the sample mean time people spend with family in a day. Then, based on a random sample of 20 people, what sample mean time people spend with family in a day would represent more than 95 % of all time people spend with family?
