State the null and alternative hypothesis, and decision rule for the following:

a.) A coach wants to know if his basketball students (n = 12) have a mean height larger than the population height of 70 inches ( s = 6). A one sample z-test will be used.

b.) A teacher wants to know if his class’s average life sciences test score is different from the district average of 78 (n = 25, s = 8). A one sample t-test will be used.

c.) 10 participants are randomly assigned to an experimental or control group (5 in each group) to test the effect of a sleeping pill on drowsiness the next day. An independent t-test will be used.

State what is the null hypothesis in a chi-square test & what is the alternative hypothesis Explain what probability is represented by the p-value. What can you conclude when p-value is below the threshold of significance (e.g., p = 0.05)? What would you conclude when p-value is above the critical value?

1: Conduct the following hypothesis test. Specify the null and alternative hypotheses, and clearly state the conclusion of the test. Use the data from 6.3.3 (?̅ = 31.7, ? = 8.7, ? = 5).
