Hypotheses testing
Is this true or false: The larger the t statistic for an upper-tail test, the more likely the null hypothesis will be rejected.
Is this true or false: Whenever two sample means are identical, any null hypothesis comparing the population means must not be rejected irrespective of the sample variances, the sample sizes, or the level of significance of the test.
Which word our of this group fits the blanks below:
Means
Central Limit
Theorem
proportions (percentage)
Z (standard normal)
Sample sizes
Standard deviations
quadruple t
double
populations
Assuming the sample proportion does not change as the sample size is increased, the value of the test statistic will ______________ if the sample size is quadrupled.
In order to take advantage of the implications proposed by the ____________________ , it is desirable to have the size of the samples from two populations both exceed 30.
