7. Sampling Distributions & Confidence Intervals: Mean

Which of the following is a point estimate for the population mean $\mu$?

Which of the following calculations is not derived from the confidence interval for a population mean $\mu$?

In the context of confidence intervals for a population mean, what happens to the expected value of the sample mean $m$ as the sample size increases?

When using the Student's $t$ distribution to construct a confidence interval for the population mean, which of the following conditions must be met?

Suppose you are constructing a conditional relative frequency table by column for a survey of students' favorite subjects. If the relative frequencies in one column are $0.17$, $0.25$, and $x$, and the sum of the column must be $1$, which value for $x$ completes the table?

When constructing a $90\%$ confidence interval for the population mean with a sample size of $n=50$, which constant should be used as the critical value if the population standard deviation is known?

If the significance level $\alpha$ is $0.10$, what is the corresponding confidence level for a confidence interval for the population mean?
