5.) Suppose a researcher collected data on the mean height of tomato plants grown in organic soil, and in computing the confidence interval for the population mean, and the margin of error was computed to be 4.86 inches. Use that to answer the following questions: a. What is the length of the confidence interval (i.e. from the first number to the second how long is the interval) if the margin of error is 4.86 inches? (2pts) b. If the data...

The sample had a mean serum cholesterol level (measured in mg/100 mL) of 192.4, with a standard deviation of 5.2. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 99% confidence interval for the mean serum cholesterol level of all women in this age group. Then complete the table below....

Use the t-distribution to find a confidence interval for a mean μ given the relevant sample results. Give the best point estimate for μ, the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed. A 99% confidence interval for μ using the sample results x¯=93.5, s=34.3, and n=15 Round your answer for the point estimate to one decimal place, and your answers for the margin of...
