When testing claims about σ or σ², the P-value method, the critical value method, and the confidence interval method are all equivalent in the sense that they will always lead to the same conclusion.

True False

Both the P-value method and the critical value method use the same standard deviation based on the claimed proportion p, so they are equivalent to each other. Is this also true about the confidence interval method.

true or false

true or false When the level of confidence and sample proportion p remain the same, a confidence interval for a population proportion p based on a sample of n = 200 will be narrower than a confidence interval for p based on a sample of n = 100.

When σ is unknown and the sample is of size n ≥ 30, there are two methods for computing confidence intervals for μ. Method 1: Use the Student's t distribution with d.f. = n − 1. This is the method used in the text. It is widely employed in statistical studies. Also, most statistical software packages use this method. Method 2: When n ≥ 30, use the sample standard deviation s as an estimate for σ, and then use the...
