Which of the following pieces of information should Peta consider when determining the confidence rating for the wiring time estimate? Select all that apply.1 pointThe electrician is confident in the amount of time they need to complete the wiringThe team's level of confidence in the time estimateThe restaurant has attempted table wiring at least once beforeThe team is still waiting for the menu update

a.Construct a 95%confidence interval estimate of the mean cost of a meal for restaurants that have a summated rating of 51. 19.857≤Y1X=×1≤26.923 (Type integers or decimals.Round to three decimal places as needed.Use ascending order.) b.Construct a 95%prediction interval of the cost of a meal for an individual restaurant that has a summated rating of 51. 4.498≤Yx=51≤42.283 (Type integers or decimals.Round to three decimal places as needed.Use ascending order.) c.Explain the differences in the results from (a)and(b).Choose the correct answer below. OA.Since there is more variation in estimating a mean value than in predicting an individual value,the confidence interval is narrower than the prediction interval,holding everything else fixed. B.Since there is more variation in estimating a mean value than in predicting an individual value,the confidence interval is wider than the prediction interval,holding everything else fixed. O C.Since there is more variation in predicting an individual value than in estimating a mean value,the prediction interval is wider than the confidence interval,holding everything else fixed. OD.Since there is more variation in predicting an individual value than in estimating a mean value,the prediction interval is narrower than the confidence interval,holding everything else fixed.

Juana is interested in estimating how long it takes students at her school to complete a maze she designed. She takes a random sample of   students and records how long it takes each of them to complete the maze. They work separately from each other, so Juana is willing to assume independence. Here are the data with summary statistics:Player     Time (minutes)     Mean   seconds Standard deviation   seconds Assume that all conditions for inference are met for this sample.Which of the following is a   confidence interval for the mean time (in seconds) it takes students to complete this maze?Choose 1 answer:Choose 1 answer:(Choice A)    A  (Choice B)    B  (Choice C)    C  (Choice D)    D (Choice E)    E

Why is the three-point time estimating technique a good way to determine a confidence rating for your time estimates?1 pointIt is a commonly used technique that everyone is familiar with.It is the time estimating technique that involves input from the most people. It ensures you have considered the best-case and worst-case conditions for a task.It removes all uncertainty from your estimate.10.Question 10
