Statistics and Null Hypothesis Questions
) Identify Whether to Use a One-tailed or Two-tailed Test Given H0: p ≥ 80% and Ha: p < 80%,
determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. 2) A car maker claims that its new sub-compact car gets better than 47 miles per gallon on the highway.
Determine whether the hypothesis test for this is left-tailed, right-tailed, or two-tailed.
3) The owner of a professional basketball team claims that the mean attendance at games is over 30,000
and therefore the team needs a new arena. Determine whether the hypothesis test for this claim is lefttailed, right-tailed, or two-tailed. 4) Interpret a Decision Based on the Results of a Statistical Test The mean age of bus drivers in Chicago is
50.2 years. If a hypothesis test is performed, how should you interpret a decision that rejects the null
hypothesis? 5) The mean age of bus drivers in Chicago is greater than 57.8 years. If a hypothesis test is performed,
how should you interpret a decision that rejects the null hypothesis?
6) The mean IQ of statistics teachers is greater than 160. If a hypothesis test is performed, how should
you interpret a decision that rejects the null hypothesis? 7) Find the critical value for a right-tailed test with α = 0.01 and n = 75.
8) You wish to test the claim that μ ≠ 22 at a level of significance of α = 0.05 and are given sample
statistics n = 35, x = 21.1, and s = 2.7. Compute the value of the standardized test statistic. Round your
answer to two decimal places.
9) Find the standardized test statistic t for a sample with n = 15, x = 7.4, s = 0.8, and α = 0.05 if H0: μ ≤
7.1. Round your answer to three decimal places. 10) Determine the critical value, z0, to test the claim about the population proportion p = 0.250 given n
= 48 and p ^ = 0.231. Use α = 0.01.
11) Find the critical X2 -values to test the claim σ2 = 4.3 if n = 12 and α = 0.05.
