Chapter 11: Inference About a Population

Explore the intricacies of hypothesis testing and inference about a population with this detailed chapter. Test your knowledge with the following true/false questions:

1. 1. To determine the p-value associated with hypothesis testing concerning the population mean μ, the value of the test statistic is essential. (True)
2. 2. Interpreting the p-value related to hypothesis testing about the population mean μ requires knowing the test statistic value. (False)
3. 3. For a sample of 15 observations requiring a 95% confidence interval estimate for μ, the appropriate t-value is 1.753. (False)
4. 4. With a sample of 18 observations necessitating a 90% confidence interval estimate for μ, the correct t-value is 1.740. (True)
5. 5. The statistic for a normally distributed sampled population follows a Student t-distribution with n degrees of freedom. (False)
6. 6. Even if the sampled population is non-normal, the t-test for the population mean μ remains valid under less extreme conditions. (True)
7. 7. An incorrect statement regarding a race car driver’s 0 to 60 mph time and a 95% confidence interval. (False)
8. 8. When constructing a 95% confidence interval for a population mean from a sample size of 20, the degrees of freedom from the t-distribution is not 20. (False)
9. 9. The t-distribution is utilized in a confidence interval for a mean when the true standard error is unknown. (True)
10. 10. The t-distribution allows for calculating confidence intervals for means for small samples when the population variance is unknown, regardless of the population distribution. (False)
11. 11. Using the t-distribution is essential to develop a confidence interval estimate for the population mean when the population standard deviation is unidentified. (True)
