(d)
Find the predicted percentage y of strikeouts for a player with an x = 0.280 batting average. (Round your
answer to two decimal places.)
(e)
Find an 80% confidence interval for y when x = 0.280. (Round your answers to two decimal places.)
%upper limit!
lower limit
(f)
Use a 5% level of significance to test the claim that 30. (Round your answers to three decimal places.)
critical t
t=
Conclusion
Reject the null hypothesis, there is sufficient evidence that differs from 0. Reject the null
hypothesis, there is insufficient evidence that 3 differs from 0.
Fail to reject the null hypothesis,
there is insufficient evidence that 3 differs from 0. Fail to reject the null hypothesis, there is sufficient
evidence that differs from 0.
