4 DECIMALS - THANK YOU!

Application Exercise:

The U.S. state of Nebraska hired an education firm to implement a program to help students in science, technology, engineering, and math (STEM).The following year, the average math SAT portion was 497 for a sample of 13 students in Nebraska.The national math SAT average is 503 with a standard deviation of 76.State legislators believe the program had the opposite effect.What can be concluded with= 0.05?

a)What is the appropriate test statistic?

---Select---

1. na
2. z-test
3. One-Sample t-test
4. Independent-Samples t-test
5. Related-Samples t-test
6. One-Way ANOVA
7. Within-Subjects ANOVA
8. Two-Way ANOVA
9. Correlation
10. Slope
11. Chi-Square GoF
12. Chi-Square Independence

b) Population:

---Select---

1. math SAT scores in Nebraska
2. national math SAT scores
3. education firm
4. students in STEM
5. Nebraska State legislators

Sample:

---Select---

1. math SAT scores in Nebraska
2. national math SAT scores
3. education firm
4. students in STEM
5. Nebraska State legislators

c)Obtain/compute the appropriate values to make a decision aboutH₀.

• Critical Value =
• Test Statistic =
• Decision:

---Select---

1. Reject H0
2. Fail to reject H0

d)If appropriate, compute the CI.If not appropriate, input "na" for both spaces below.

[,]

e)Compute the corresponding effect size(s) and indicate magnitude(s).

If not appropriate, input and select "na" below.

• d=
• Magnitude:

---Select---

1. na
2. trivial effect
3. small effect
4. medium effect
5. large effect

• r²=
• Magnitude:

---Select---

1. na
2. trivial effect
3. small effect
4. medium effect
5. large effect

f)Make an interpretation based on the results.

1. Students from the nation had significantly lower math SAT scores than students from Nebraska.
2. Students from the nation had significantly higher math SAT score than students from Nebraska.
3. The program did not have a significant effect.
