Question

Mathew is interested in the relationship between a learning game Power Physics and Creativity. He has developed an instrument for testing Creativity. After some initial pilot tests, he and Russell work out that the hypothesized mean creativity score should be 7 and the standard deviation for creativity scores should be around ? = 2.3, Standard error = 0.5019 Probability of observing a mean posttest score that is equal to or greater than that observed by Matthew is 0.5 There is a 5% chance of a type 1 error The mean posttest score for the pilot sample is 7.6.

At the alpha level of .05, what should Mathew conclude about the mean posttest score based on the pilot data?

Answer 1

Claim: The hypothesized mean creativity score should be 7.

Let =true mean creativity score.

There is sufficient evidence to conclude that the true mean creativity score is 7.
