True or False: A stratified random sample can be used to ensure underrepresented populations are represented in a study.

True or False: If a 90% confidence interval for the mean is (75.3 to 80.9), we would reject H₀: =70 in favor of H₁: 70 at = 0.05

True or False: In logistic regression, the predictors are dichotomous, and the outcome is a continuous variable.

True or False: If a 95% confidence interval for the difference in two independent means is (2.1 to 4.5), there is no significant difference in means.

True or False: Assume a doctor uses a specific form of mesh to repair all hernias in his hernia patients. The makers of the mesh found there was an error that occurred while making the mesh, and the hernia mesh has a 45% chance of failure. The doctor has treated 7 patients with the mesh so far; thus, the probability that the mesh does not fail in all seven patients is .0152.
