Outcome	Outcome Met/Not Met/In Process	Evidence
1.Statistically significant difference between treatment and comparison groups in mathematics grades 3–8		T=3.626 P<3.0533536280097256E-4
2.Statistically significant difference between treatment and comparison groups in science grades 4 & 8		T=1.77 P<0.07857488293853984
3a.Statistically significant difference between treatment and comparison groups in math Regents exams		T=-2.315 P<.015
3b.Statistically significant difference between treatment and comparison groups in science Regents exams		T=2.227 P<0.022816361682797652
4.Positive trend data in percentage of students enrolling in secondary math and science courses		Analysis of enrollment data for high school math and science courses reveal an overall increase of 684 students or 12.4% increase in enrollment

My question is based on the chart above : In the comments section following Goal #1, based upon your analysis of the evidence, summarize the findings for Goal #1. My comments should include any suggestions for further research or dat gathering based on questions arising out of these data that I feel still need to be addressed.

The problem is I am not good with this at all. Any help would be greatly appreciated.

Answer 1

First we consider level of significance = alpha = 0.05

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

Given that,

T = 3.626

P-value < 3.053E-04 = 0.0003053 < alpha

Reject H0 at 5% level of significance.

Given statement is correct.

Outcome met in this process.

Statistically significant difference between treatment and comparison groups in science grades 4 & 8

T = 1.77

P-value < 0.07857

P-value > alpha

Aceept H0 at 5% level of significance.

Given statement is incorrect.

Outcome doesn't met in this process.

.Statistically significant difference between treatment and comparison groups in math Regents exams

T = -2.315

P-value < 0.015 < alpha

Reject H0 at 5% level of significance.

Given statement is correct.

Outcome met in thid process.

Statistically significant difference between treatment and comparison groups in science Regents exams

T = 2.227

P-value < 0.0228 < alpha

Reject H0 at 5% level of significance.

Given statement is correct.

Outcome met in thid process.

Positive trend data in percentage of students enrolling in secondary math and science courses

Analysis of enrollment data for high school math and science courses reveal an overall increase of 684 students or 12.4% increase in enrollment

This is also correct statement.

Positive correlation means as one variable increases/decreases other variable also increases/decreases.
