Let x be a random variable that represents the percentage of successful free throws a professional basketball player makes in a season. Let y be a random variable that represents the percentage of successful field goals a professional basketball player makes in a season. A random sample of n-6 professional basketball players gave the following information. x 67 64 75 86 73 73 y 44 40 48 51 44 51 (a) Verify that Ix 438, 2y278, E32264, 2y-12978, Exy-20429, and rx 0,804. Ey Exy (b) Use a 5% level of significance to test the claim that p > 0. (Round your answers to two decimal places.) critical t Conclusion O Reject the null hypothesis, there is sufficient evidence that p > 0. O Reject the null hypothesis, there is insufficient evidence that p > 0. O Fail to reject the null hypothesis, there is insufficient evidence that p>0. O Fail to reject the null hypothesis, there is sufficient evidence that p>0. (c) Verify that 52.9363, a 12.351, b 0.4655, and x = 73.000. 5, $:10 PM Ix² Iy²
O Fail to reject the null hypothesis, there is sufficient evidence that p > 0. (c) Verify that 5-2.9363. a 12.351, 60.4655, and x 73.000. (d) Find the predicted percentage of successful field goals for a player with x=65% successful free throws. (Round your answer to two decimal places) (e) Find a 90% confidence interval for y when x 65. (Round your answers to one decimal place.) lower limit upper limit (f) Use a 5% level of significance to test the claim that > 0. (Round your answers to two decimal places.) critical t Conclusion O Reject the null hypothesis, there is sufficient evidence that > 0. O Reject the null hypothesis, there is insufficient evidence that #> 0. > 0. O Fail to reject the null hypothesis, there is insufficient evidence that O Fall to reject the null hypothesis, there is sufficient evidence that > 0. (g) Find a 90% confidence interval for . (Round your answers to three decimal places) M
Conclusion O Reject the null hypothesis, there is sufficient evidence that > 0. Reject the null hypothesis, there is insufficient evidence that >0. O Fail to reject the null hypothesis, there is insufficient evidence that > 0. O Fail to reject the null hypothesis, there is sufficient evidence that // > 0. (9) Find a 90% confidence interval for f. (Round your answers to three decimal places.) lower limit upper limit Interpret its meaning. O For every percentage increase in successful free throws, the percentage of successful field goals increases by an amount that falls outside the confidency interval. O For every percentage increase in successful free throws, the percentage of successful field goals decreases by an amount that falls outside the confidence interval. O For every percentage increase in successful free throws, the percentage of successful field goals increases by an amount that falls within the confidence interval. O For every percentage increase in successful free throws, the percentage of successful field goals decreases by an amount that falls within the confidence interval.
