Question

A research team is willing to assume that systolic blood pressures in
a certain population of males are approximately normally distributed
with a standard deviation of 16. A simple random sample of 10 males is
drawn from this population and their systolic blood pressure reading
taken. At the .05 level of significance, derive the Uniformly Most
Powerful Test for testing the hypotheses;
Null hypothesis =130 vs alternative vs hypothesis > 130

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
