• 37.5%

• 33.33%

Consider the following scores: 1, 2, 2, 2, 3, 3, 4, 4, 6, 7, 8, 10. What is the range?

• 3

• 3.5

• 9

• No answer

It is used to determine if the mean performance of one or more alternatives is statistically significantly different.

• T-Test

• Mann Whitney Test

• Duncan Multiple Range Test

• ANOVA

Which of the following is used to test Non Parametric Data?

• ANOVA

• Chi Square

• T-Test

• Duncan Multiple Range Test

Which of the following p-values will lead us to reject the null hypothesis if α = 0.05?

• 0.150

• 0.025

• 0.051

• 0.100

Suppose we reject H₀ at 0.05 level. Which α-values do we also reject H₀?

• 0.03

• 0.04

• 0.02

• 0.06

Suppose that a hypothesis test is rejected at the 0.10 level, also at 0.05, but not at 0.01. What is the most accurate statement about the p-value?

• 0.01 < p-value < 0.05

• p-value = 0.10

• p-value = 0.01

• 0.05 < p-value < 0.10

If the p value is less than α in a two-tail test:

• Null should be rejected

• No conclusion

• One-tail test should be used

• Null should not be rejected

• H₀: μ < 65,000; H₁: μ ≥ 65,000
