These symbols are used to denote a null hypothesis EXCEPT

• <

• ≥

• Ho

• =

Type I error is committed when _____.

• the null hypothesis is false and rejected

• true null hypothesis is rejected

• the null hypothesis is true and not rejected

• there was a failure to reject a false null hypothesis

Given that all assumptions are satisfied, the researcher should proceed with ___.

• Wilcoxon Signed-Ranks Test

• Non-parametric Test

• Parametric Test

• Kruskal-Wallis Test

If the p-value is 0.009, and the level of significance is 0.05, what should be your decision?

• Fail to reject Ha

• Reject Ha

• Fail to reject Ho

All of these are characteristic of a normal distribution EXCEPT

• • bell-shaped and symmetric about μ

• • has a maximum of x= μ

• • asymptotic with respect to the x-axis and unimodal

• skewed to the left
