Use Table A.2 to find the critical value and rejection region in each of the following situations. Then determine whether the null hypothesis would be rejected. In each case, the null hypothesis is Ho: H = 100. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) (a) H: µ > 100, n = 29, a = 0.05, test statistic t = 2.33 Find the critical value and rejection region. rejection region t > 1.7 t < -1.7
Consider a test of H 0: μ = 50 performed with the computer. SPSS reports a two-tailed p-value of 0.0574. Come to the appropriate conclusion for the given situation: H a: μ <50, z = -1.9, α = 0.05

Consider the OLS regression equation: ŷ = 0 + Â₁×1 + B₂X2 + Â33. If the R² is close to zero, it implies O x3 is not highly correlated with X₁ O B3 is likely to be biased O B3 is likely to be unbiased O that we expect the estimate of B3 to be noisy.
Consider the demand for Fresh Detergent in a future sales period when Enterprise Industries' price for Fresh will be x1 = 3.70, the average price of competitors' similar detergents will be x2 = 3.90, and Enterprise Industries' advertising expenditure for Fresh will be x3 = 6.50. A 95 percent prediction interval for this demand is given on the following JMP output: %3D Predicted Lower 95% Upper 95% Mean Demand Upper 95% Indiv Demand StdErr Lower 95% Demand Mean Demand Indiv Demand Indiv Demand 31 8.4106503477 8.3143172822 8.5069834132 0.2393033103 7.9187553487 8.9025453468 E Click here for the Excel Data File; (a) Find and report the 95 percent prediction interval on the output. If Enterprise Industries plans to have in inventory the number of bottles implied by the upper limit of this interval, it can be very confident that it will have enough bottles to meet demand for Fresh in the future sales period. How many bottles is this? If we multiply the number of bottles implied by the lower…
