Question

Heights of NBA Players. The average height of an NBA player is 6.698 feet with a standard deviation of 0.45 feet. A random sample of 30 players’ heights from a major college basketball program found the mean height was 6.75 feet. At alpha = 0.05, a researcher wants to determine if there is sufficient evidence to conclude that the mean height differs from 6.698 feet. What is the test value of the study?

Answer 1

Solution

$$Test \space value = {\bar{x} - \mu \over { SD \over \sqrt {n}}}$$

$$={6.75 - 6.698 \over {0.45 \over \sqrt {30}}}$$

Test value = 0.6329
