Stat 101 LE 3 Review

Given the computed p-value to be 0.12, then Ho will be rejected at a 10% level of significance.

• True

• False

Fixing all other factors constant, a 90% confidence interval is narrower than a 95% confidence interval.

• True

• False

If Ho is not rejected at a 0.10 level of significance, then Ho will also not be rejected at the 0.01 level of

significance.

• True

• False

If a 90% confidence interval estimate for the population mean final exam score of all Stat 101

students this semester is computed to be (38, 42), then around 90% of these students have scores

ranging from 38 to 42.

• True

• False

• True

• False

The unbiased estimator for a certain parameter is unique.

• True

• False

We decide to reject Ho if the value of the test statistic belongs in the critical region.

• True

• False

The Central Limit Theorem requires the population from where the sample came from to at least

be symmetric like a normal distribution.

• True

• False

A low standard error of an estimator implies a low reliability of that estimator.

• True

• False

As the degrees of freedom increases, the t-distribution approaches the standard normal

distribution.

• True

• False
