MULTIPLE CHOICE We would like to assess if, on average, there is a significant difference in the amount time (in seconds) it takes to write a full name (difference = writing hand – non-writing hand) for all first-grade children in the US . The hypotheses are: H0: μd = 0 versus Ha: μd ≠ 0 and a 10% significance level is selected.After conducting the appropriate test, the researcher fails to reject H0 at a 10% significance level. Using the same data, which of the following intervals would be a reasonable 90% confidence interval for μd? [(-2.1, -.4), (.53, 4.7), or -.4, 1.3) ] ? The research prefers to use QQ plots over histograms for checking normality assumptions in general. How many QQ plots would the researcher need to make for this study? [1, 2, or 3] Alpha (?α ) is the probability of [incorrectly or correctly] concluding that μd ≠ 0.

MULTIPLE CHOICE We would like to assess if, on average, there is a significant difference in the amount time (in seconds) it takes to write a full name (difference = writing hand – non-writing hand) for all first-grade children in the US . The hypotheses are: H₀: μ_d = 0 versus H_a: μ_d ≠ 0 and a 10% significance level is selected.

After conducting the appropriate test, the researcher fails to reject H₀ at a 10% significance level. Using the same data, which of the following intervals would be a reasonable 90% confidence interval for μ_d? [(-2.1, -.4), (.53, 4.7), or -.4, 1.3) ] ?
The research prefers to use QQ plots over histograms for checking normality assumptions in general. How many QQ plots would the researcher need to make for this study? [1, 2, or 3]
Alpha (?α ) is the probability of [incorrectly or correctly] concluding that μ_d ≠ 0.
