Answer Happy

A sample of 95 results in 57 successes. [You may find it useful to reference the z table. a. Calculate the point estimate for the population proportion of successes. (Do not round intermediate calculations, Round your answer to 3 decimal places.) Point estimate b. Construct 99% and 90% confidence intervals for the population proportion (Round Intermediate calculations to at least 4 decimal places. Round "x" value and final answers to 3 decimal places.) Confidence Level 99% Confidence interval to to 90% c. Can we conclude at 99% confidence that the population proportion differs from 0.680? No, since the confidence interval does not contain the value 0.680 No, since the confidence interval contains the value 0.680 Yes, since the confidence interval does not contain the value 0680. Yes, since the confidence interval contains the value 0.680. d. Can we conclude at 90% confidence that the population proportion differs from 0.680? No, since the confidence interval contains the value 0.680 No, since the confidence interval does not contain the value 0.680, Yes, since the confidence interval contains the value 0.680. Yes, since the confidence interval does not contain the value 0.680.
