7) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test ie, describe the values of the test statistic that would result in rejection of the null hypothesis Suppose you wish to test the claim that the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n-15 and a significance level of a-001, what criterion would be used for rejecting the null hypothesis...

Select all that are true, if p < .05 1.) the null hypothesis should be accepted 2.)the test results are significant 3.) the results are not likely due to random chance 4.) the null hypothesis should be rejected 5.) you would expect to find results more extreme less than 5 times out of 100

stats Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor...

A distribution of values is normal with a mean of 170 and a standard deviation of 12. From this distribution, you are drawing samples of size s7. Find the interval containing the middle-most 50% ofsample means: 171.3 Enter your answer using interval notation. In this context, either inclusive or exclusive intervals would be acceptable. Your numbers should be accurate to 1 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
