Answer 1

The probability of concluding group means are significantly

different when they really are not has a value of Type I error.

(Ans).

The value(s) which separate(s) the rejection region from the

non-rejection region is(are) the critical value(s). (Ans).

Reducing Statistical power makes a Type II error more likely,

as, Power = 1 - P(Type II error). (Ans).

Finding a significant difference in the sample when there is no

difference in the population is a sampling error. (Ans).

A result is statistically significant is the p-value is less than

the level of significance. (Ans).

The null hypothesis is a statement if no relationship that is

assumed to be true when calculating a test-statistic. (Ans).

A < B, is a directional alternative (one-sided, less than).
