4.Positive trend data in percentage of students enrolling in secondary math and science courses I have this assignment and I have no idea what none of this mean. I need all the help I can get. Thank you in advance		Analysis of enrollment data for high school math and science courses reveal an overall increase of 684 students or 12.4% increase in enrollment.

Answer 1

Solution1:

1.Statistically significant difference between treatment and comparison groups in mathematics grades 3–8

OUTCOME :MET set alpha=0.05

T=3.626 P<3.0533536280097256E-4

since p value is less than 0.05,reject Ho and accept Ha .there is sufficient statistical evidence at 5% level of significance to conclude that there are differences between treatment and comparison groups in mathematics grades 3–8.

Solution2:

Outcome

NOT MET

T=1.77

P<0.07857488293853984

Since p value is greater than alpha=0.05.Fail to reject H0 and can conclude that difference between treatment and comparison groups in science grades 4 & 8 are NOT STATISTICALLY SIGNIFICANT. Solutio3a: OUTCOME :MET T=-2.315 alpha=0.05 P<.015 Since p value is less than alpha,statistical decsion is to reject H0 and accept H1 and can conclude that difference between treatment and comparison groups in math Regents exams are statistically significant Solution3B: OUTCOME :MET T=2.227 alpha=0.05 P<0.022816361682797652 Since p value is less than alpha,statistical decision is to reject H0 and accept Ha and can conclude that difference between treatment and comparison groups in science Regents exams are statistically significant Solution4: OUTCOME:MET since there is an increase of 12% in erollment from previous year in secondary math and science courses.
