Assignment:
Objective:
The team determined that to confirm the validity of their screening experiment they should compare the test score results for some students that were at both the high setting and low setting within the last three years. This would allow them to compare the impact of the factors for individual students.
Instructions:
For each of the three factors for which data is provided:
a. Write a null and alternative hypothesis statement about the impact of the factor on student test scores.
b. Test each of the hypotheses at 90% confidence level. Note: you should know the tool to use. If you are struggling deciding which analysis tool to use contact your instructor for guidance. There is paired data. And, we want to see which of the three (style, community involvement, or a two-parent home) has moved the average test scores the most. There is also a mention of a hypothesis test and a degree of confidence sought after.
c. Based on the results of steps a. and b., determine whether or not each of three factors have a significant impact on student test scores.
Data:

14 84 89 14 82 79 14 83 86
15 69 78 15 74 79 15 78 75
So the results are:
Write the null hypothesis statement for STYLE
Write the alternate hypothesis statement for STYLE
Does STYLE have significance?
Write the null hypothesis statement for COMM INVOLVEMENT
Write the alt. hypothesis statement for COMM INVOLVEMENT
Does COMMUNITY INVOLVEMENT have significance?
Write the null hypothesis statement for 2 parent family
Write the alt. hypothesis statement for 2 parent family
Do 2 PARENT FAMILY not have significance?
