Question 26 (1 point)

When the null hypothesis is rejected in ANOVA, it always implies:

At least one population variance is different

At least one population mean is different.

All the population means are equal.

All the population means are different.

All the population variances are different.

Question 27 (1 point)

Which of the following is (are) false?

Beta 0 is used to denote the population slope.

Beta 1 is used to denote the intercept.

An r value close to 0 indicates a very high level of linear correlation.

All of the above are false.

A and B are false.

Solution:

26.

When the null hypothesis is rejected in ANOVA, it always implies:

At least one population mean is different.

Explanation:

In ANOVA our null and alternative hypothesis is,

H0: All the means are equal

Ha: At least one population mean is different.

Decision: If null hypothesis is rejected, that means alternative hypothesis is accepted.

That is , At least one population mean is different.

27. Here ,

All of the above are false. This option is correct.

Explanation:

Beta 0 is used to denote the intercept.

Beta 1 is used to denote the population slope

An r value close to 0 indicates a low level of linear correlation.
