Confidence Interval for One Population Mean In 1903, a paper published by Abigail Camp Dimon, discussed the effect of environment on the shape and form of two sea snail species. Nassa obsoleta and Nassa trivittata. One of the variables that Dimon considered was the length of the shell. A random sample of 256 N. trivittata specimens was selected. The average shell length for the sample was 12 mm., with a standard deviation of 4 mm. Find the 95% confidence interval for the average shell length of all N. trivittata sea snails. What is the margin of error used to calculate this interval? Do not round.
You are interested in finding a 99% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 12 randomly selected non-residential college students. Round answers to 3 decimal places where possible. 18 20 20 24 5 28 10 13 5 24 11 11 b. With 99% confidence the population mean commute for non-residential college students is between ? and ? miles. c. If many groups of 12 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean number of commute miles and about ? percent will not contain the true population mean number of commute miles.
