Please if you can't help with all parts please skip and please provide explanation how values come from wherever u derive excel or table. A sample of 135 results in 108 successes. (You may find it useful to reference the z table.) a. Calculate the point estimate for the population proportion of successes. (Round final answer to 3 decimal places.) b. Construct the 99% and the 95% confidence intervals for the population proportion. (Round final answer to 3 decimal places.) c. Can we conclude at 99% confidence that the population proportion differs from 0.860? multiple choice 1 No, since the confidence interval does not contain the value 0.860. No, since the confidence interval contains the value 0.860. Yes, since the confidence interval does not contain the value 0.860. Yes, since the confidence interval contains the value 0.860. d. Can we conclude at 95% confidence that the population proportion differs from 0.860? multiple choice 2 No, since the confidence interval contains the value 0.860. No, since the confidence interval does not contain the value 0.860. Yes, since the confidence interval contains the value 0.860. Yes, since the confidence interval does not contain the value 0.860.
