Blood pressure is normally distributed.Using a sample size of 15 what is the mean of the sample mean, state standard deviation of the sample mean, and find the probability that the sample mean blood pressure is more the 135mmHgWould it be Unusual to find sample mean of 15 people with blood pressure more than 135mmHg?

If you did find a sample mean for 15 people to be more than 135mmHg what might you conclude?
