Which of the following is not an assumption for one-way analysis of variance?
The p populations of values of the response variable associated with the treatments have equal variances.
The samples of experimental units associated with the treatments are randomly selected.
The experimental units associated with the treatments are independent samples.
The number of sampled observations must be equal for all p treatments.
The distribution of the response variable is normal for all treatments.
Compute the p-value associated with the above sample results, and explain what conclusion can be drawn bases on the p-value?
Find out the sample size raised by mean also standard deviation, a sampling distribution may approach among which of the following values.
Diagnosis tests of medical conditions have several results. The test result can be positive or negative, whether or not a patient has the condition.

At a recent meeting of educational researchers comparison were made between the type of college freshmen attend and the numbers who drop out. Use a significance level of .05 and determine if the type of school and the drop out rate are independent.
The State Transportation Department is interested in estimating the proportion of vehicle owners that are operating vehicles without the required liability insurance.
