Assuming that the population is normally distributed, construct a 90% confidence interval for the population mean, based on the following sample size of n = 5. 1, 2, 3, 4, and 17 D Change the number 17 to 5 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval. Find a 90% confidence interval for the population mean, using the formula or calculator. sus (Round to two decimal places as needed.) Change the number 17 to 5. Find a 90% confidence interval for the population mean, using the formula or calculator. Osus (Round to two decimal places as needed.) What is the effect of an outlier on the confidence interval? O A. The presence of an outlier in the original data decreases the value of the sample mean and greatly decreases the sample standard deviation, narrowing the confidence interval. O B. The presence of an outlier in the original data increases the value of the sample mean and greatly decreases the sample standard deviation, narrowing the confidence interval. OC. The presence of an outlier in the original data increases the value of the sample mean and greatly inflates the sample standard deviation, widening the confidence interval. O D. The presence of an outlier in the original data decreases the value of the sample mean and greatly inflates the sample standard deviation, widening the confidence interval.

You work as a health inspector and must visit each of the 15 restaurants in town once each week, In how many different orders can you make these inspections?

A doctor receives two invoices for an order including gloves and masks. The first order cost $605 and included 2000 gloves and 500 masks while the second order of 10000 gloves and 600 masks cost $916 dollars. The invoice does not show the cost of the gloves or masks. Find the cost of each glove and of each mask.
