True
False
Question 14
For all tests of hypothesis, the probability of rejecting the null hypothesis is a function of
This probability completely depends upon alpha and type of test
the alpha level and the use of one or twotailed tests
Question 15
The Central Limit Theorem states that as sample size becomes large the population distribution becomes normal
The CLT states that as n tends to infinity the distribution tends to normal
True
Question 16
The area between the mean and a Z score of + 1.50 is 43.32%. This score is higher than ________ of the scores in the distribution.
Area below mean is 50%
Area below the point = 50 + 43.32 = 93.32%
Question 17
Parameter is a numerical descriptive measure of a sample, while a statistic is a numerical descriptive measure of a population.

False
