Question
I have the first two parts but can someone help find the claim at 0.01 significance level? Thanks!
![Many high school students take the SAT's twice; once in their Junior year and once in their Senior year. In a sample of 200 such students, the average of the differences was 33 points with a standard deviation of 28.2843 points.
Test the claim that retaking the SAT increases the score on average by more than 30 points.
(a) Find the test statistic.
\[ 1.50 \]
(b) Test the claim at the 0.10 significance level.
Critical value:
\[ 1.286 \]
Is there sufficient data to support the claim?
- \[ \checked \] Yes
- \[ \square \] No
(c) Test the claim at the 0.01 significance level.
Critical value:
\[ \] (Box left blank)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe99c8c3a-6178-4c9d-bb99-e1d1268eab01%2F0062252a-9e8d-4263-8cae-9718db013881%2Fupn48gp_processed.jpeg&w=3840&q=75)
