A marketing research company is estimating the average total compensation of CEOs in the service industry. Data were randomly collected from 18 CEOs and the 90​% confidence interval for the mean was calculated to be ( 2181260, 5836180). Explain what the phrase ​"90​% ​confident" means.

A. 90​% of the similarly constructed intervals would contain the value of the sample mean.

B. 90​% of the sample means from similar samples fall within the interval.

C. 90​% of the population values will fall within the interval.

D. In repeated​ sampling, 90​% of the intervals constructed would contain mu.

    Question 4 Item 4 A civil engineer tested concrete samples to investigate the difference in strength, in newtons per square millimeter (N/mm2)(N/mm2), between concrete hardened for 21 days and concrete hardened for 28 days. The engineer measured the strength from each sample, calculated the difference in the mean strength between the samples, and then constructed the 95 percent confidence interval, (2.9,3.1)(2.9,3.1), for the difference in mean strengths. Assuming all conditions for inference were met, which of the following is a...
