The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution.

Test H0 : μ=8 vs Ha : μ≠8 when the sample has n=70, x¯=11.9, and s=0.80 with SE=0.10.

Find the value of the standardized z-test statistic.

Round your answer to two decimal places.

. The final scores of games of a certain sport were compared against the final point spreads established by oddsmakers. The difference between the game outcome and point spread​(called a​ point-spread error) was calculated for 225 games. The sample mean and sample standard deviation of the​ point-spread errors are overbarx=1.4 and s=11.3. Use this information to test the hypothesis that the true mean​ point-spread error for all games is larger than0. Conduct the test at α=0.10 and interpret the result....

A mixture of pulverized fuel ash and Portland cement to be used for grouting should have a compressive strength of more than 1300 KN/m2. The mixture will not be used unless experimental evidence indicates conclusively that the strength specification has been met. Suppose compressive strength for specimens of this mixture is normally distributed with σ = 67. Let μ denote the true average compressive strength. (a) What are the appropriate null and alternative hypotheses? H0: μ > 1300 Ha: μ...
