List the 5 steps of hypothesis testing and explain the logic and procedure of each.

Based on the information provided for this hypothesis test, what decision should you come to? (Assume that the population is normally distributed.)

Note that you need to complete the hypothesis testing tests you just outlined above in relation to this example.

Be sure to include the cut-off sample score, the sample score on the comparison distribution, and the conclusion you reach. Mean=5; SD=1, Sample Score=7, .05 level of significance, one-tailed Figure the mean and the standard deviation of the distribution of means for each of the following: Population Sample Size M SD2 N a. 100 40 10 b. 100 10 20 c. 50 10 10

For each of the following studies, the samples were given an experimental treatment and the researchers compared their results to the general population (all populations are normally distributed). For each, carry out a Z test using the 5 steps of hypothesis testing for a two-tailed test.

Figure the 95% confidence intervals for each study.

Be sure your answers for each study include the: SDM, Cut-off Z, Sample Z, Conclusion and 95% Confidence Interval.
