A quality control specialist for a restaurant chain takes a random sample of size 11 to check the amount of soda served in the 16 oz. serving size. The sample mean is13.50 with a sample standard deviation of 1.58. Assume the underlying population is normally distributed. We wish to construct a 95% confidence interval for the truepopulation mean for the amount of soda served.What is the error bound? (Round your answer to two decimal places.)0.934

An analyst is testing whether the mean for a population is different than 54. The population is normally distributed with population standard deviation of 13. The analyst takes a sample of size 24 and computes the sample mean to be 50. What is the p-value for the test? (Round to three decimal places.)
Suppose you buy a new car whose advertised mileage is 20 miles per gallon (mpg). After driving your car for several months, you find that its mileage is 16.5 mpg. You telephone the manufacturer and learn that the standard deviation of gas mileages for all cars of the model you bought is 1.02 mpg. a. Find the z-score for the gas mileage of your car, assuming the advertised claim is correct. b. Does it appear that your car is getting unusually low gas mileage?

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 5.3 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 1030 samples is 5.4 ppm. Assume the standard deviation is known to be 1.1. Does the data support the claim at the 0.01 level? Step 4 of 5 : Enter the decision rule.
