A biologist examines 6 geological samples for lead
concentration. The mean lead concentration for the sample data is
0.714 cc/cubic meter with a standard deviation of 0.0126. Determine
the 90% confidence interval for the population mean lead
concentration. Assume the population is approximately normal.
Find the critical value that should be used in constructing the
confidence interval. Round your answer to three decimal places.

You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Which interval is wider? If convenient, use technology to construct the confidence intervals. A random sample of 43 gas grills has a mean price of $626.50. Assume the population standard deviation is $58.70. The 90% confidence interval is ( , ). (Round to one decimal place as needed.) The 95% confidence interval is (...

Given two dependent random samples with the following results: Population 1 41 33 18 34 42 39 50 Population 2 50 29 29 28 47 24 44 Use this data to find the 95% confidence interval for the true difference between the population means. Let d=(Population 1 entry)−(Population 2 entry) . Assume that both populations are normally distributed. Step 1 of 4: Find the mean of the paired differences, d ‾ . Round your answer to one decimal place. Step...
