Which of these is not an assumption of the z test? a. The dependent variable is measured on a scale measure b. The distribution of the sample is normal c. Participants were randomly selected from the population d. The distribution of the population is approximately normal
Which of these is not an assumption of the z test?
a. The dependent variable is measured on a scale measure
b. The distribution of the sample is normal
c. Participants were randomly selected from the population
d. The distribution of the population is approximately normal
Followings are the Explanation of the question
Z - test:- When the Population standard deviation known then we use the Z test
1) One Sample Z test
2) Two Sample Z test
Followings are the Assumption for a Z test
1) We know about the Population Distribution
2) Distribution of the Population follows Approximately Normal Distribution
3) Also Sample Data follows the Normal Distribution
4) When the Sample Size Lager (Greater Than 30) and data follows the Normal distribution then we use the Z test
5) Select the the Sample From Random Samples ( Participants were randomly selected from the population)
