Question 14

1. For all tests of hypothesis, the probability of rejecting the null hypothesis is a function of

 A. the size of the observed differences B. the alpha level and the use of one- or two-tailed tests C. sample size D. all of the above

Question 15

True

False

Question 16

1. 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.

 A. 51.50% B. 93.32% C. 43.32% D. 57.68%

Question 17

True

False

Question 14

1. 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 two-tailed tests

Question 15

1. 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

1. 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

1. Parameter is a numerical descriptive measure of a sample, while a statistic is a numerical descriptive measure of a population.

The parameter is population value and statistics is sample value

False
