- 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 99% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi? 0.58, 0.75, 0.10, 0.88, 1.25, 0.52, 0.82A food safety guideline is that the mercury in fish should be below 1 part per million (ppm).

Assume the population is normally distributed and use a t-distribution to construct a 80% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean u is (Round to one decimal place as needed.)
- A large box contains 10000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm and the standard deviation is 0.24 mm. Is the following statement true or false?

- A factory hiring people to work on an assembly line gives job applicants a test of manual agility. This test counts how many strangely shaped pegs the applicant can fit into matching holes in a one-minute period. The table below summarizes data collected for 90 applicants - 45 men and 45 women: Male Female n 45 45 Mean 20.17 19.02 Std Dev 2.388 2.712 Find separate 90% confidence intervals for the average number of pegs males and females can correctly place (note: these intervals are one-sample intervals from previous material!). The appropriate t-critical point for both intervals is t = 1.68. The 90% confidence interval for males is: lower limit = , upper limit = The 90% confidence interval for females is: lower limit = , upper limit = What do these intervals suggest about gender differences in manual agility? The individual intervals suggest females place a greater mean number of pegs because most the interval for this gender is greater than the interval for…A food safety guideline is that the mercury in fish should be below 1 part per million (ppm).
