When constructing a confidence interval using the t distribution, as you increase the sample size,
the width of the confidence interval will also increase.
True
O False
The alpha (a) level of a two-tailed z test is set at 0.05. The corresponding p-value calculated from
your test statistic is 0.2462. Given the p-value, the most appropriate decision in this scenario
would be to reject the null hypothesis of the test.
True
O False
The mean of the sampling distribution (also known as the mean of all sample means) is equal to the
population mean.
