A food safety guideline is that the mercury in fish should be below 1 part per million (ppm). Listed below are the amounts of mercury (ppm) found in tuna sushi sampled at different stores in a major city. Construct a 95% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi? 0.51 0.79 0.09 0.97 1.37 0.54 0.90 What is the confidence interval estimate of the population mean μ? ☐ ppm<μ< ☐ ppm (Round to three decimal places as needed.) The pulse rates of 174 randomly selected adult males vary from a low of 41 bpm to a high of 109 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 98% confidend that the sample mean is within 3 bpm of the population mean. Complete parts (a) through (c) below. a. Find the sample size using the range rule of thumb to estimate σ. n = (Round up to the nearest whole number as needed.) Samples of DNA are collected, and the four DNA bases of A, G, C, and T are coded as 1, 2, 3, and 4, respectively. The results are listed below. Construct a 95% confidence interval estimate of the mean. What is the practical use of the confidence interval? 2, 2, 1, 4, 3, 4, 3, 4, 4, 1 What is the confidence interval for the population mean μ? ☐ <μ<☐ (Round to one decimal place as needed.)
