According to the WHO MONICA Project the mean systolic blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg (Kuulasmaa, Hense & Tolonen, 1998).Systolic blood pressure is normally distributed.

a.)TRUE or FALSE:The random variable is defined as systolic blood pressure of a person in China.

b.)For a sample of size 15, state the mean of the sample mean.

c.)For a sample of size 15, state the standard deviation of the sample mean (the "standard error of the mean").

d.)Suppose a sample of size 15 is taken.Find the probability that the sample mean systolic blood pressure is more than 135 mmHg.

For part (a):Enter TRUE or FALSE

For parts (b) through (d), enter answer in decimal form rounded to nearest thousandth (3 places after decimal).
