1. State the dependent variable
2. Explain whether Lucy should use a one-tailed or a two-tailed z-test and explain why?
3. State the null hypothesis in words
4. State the alternative hypothesis in words (not formulas).
5. Calculate the obtained z-score by hand. Describe your calculations (i.e., show your work).
6. When alpha is set at .05, the critical value is 1.96. Should the null hypothesis be retained or rejected? Explain why
7. Are the results statistically significant? How do you know?
8. What should Lucy conclude about Monica's reading comprehension score in comparison to the population?
9. Lucy is excited that she remembers how to compute a z-score and does some additional computations to find Monica's z-score in math. You can find the information you need in the Weekly Data Set forum. Use it to calculate Monica's raw math score by hand. Provide your calculations in your Assignment submission (i.e., explain your work).

Monica's reading comprehension score = 10

Mean fourth grade reading comprehension score = 8

Standard deviation of the fourth grade's reading comprehension = 2

Monica's z-score in math = 1.5

Mean fourth grade math score = 7

Standard deviation of the fourth grade's math scores = 1.0
