Question

(42) – (45): True or False?

42) The sample statistic is at the center of a confidence interval for that statistic.

43) In a hypothesis test, increasing the significance level increases the chance of making a type 1 error.

44) Failure to reject the null hypothesis test in a hypothesis test implies strong support for the null hypothesis.

45) When no prior belief about a population characteristic is held, construction of a confidence interval, rather than the use of hypothesis testing, is used to estimate the population characteristic.

Separate Question:

46) For the following pairs, indicate which comply with the rules for setting up hypotheses.

A) Ho: ā = 42, Ha: ā < 42 B) Ho: p = 0.4, Ha: p > 0.4 C) Ho: μ = 28, Ha: μ ≥ 28

D) Ho: μ = 8, Ha: μ ≠ 8 E) Ho: s = 7, Ha: s < 7
