12. Medicare would like to test the hypothesis that the average monthly rate for one-bedroom assisted-living facility is equal to $3,300. A random sample of 12 assisted-livingfacilities had an average rate of $3,690 per month. The standard deviation for this sample was $530. Medicare would like to set a = 0.05. The conclusion for this hypothesistest would be that because the absolute value of the test statistic isQuestion options:A) more than the absolute value of the critical value, we can conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.B) less than the absolute value of the critical value, we can conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.C) more than the absolute value of the critical value, we cannot conclude that the average monthly rate for an assisted-living facility is not equal to $3,300.D) less than the absolute value of the critical value, we cannot conclude that the average monthly rate for an assisted-living facility is not equal to $3,300. 9. The Department of Transportation would like to test the hypothesis that the average age of cars on the road is less than 10 years. A randomsample of 50 cars had an average age of 9.5 years. It is believed that the population standard deviation for the age of cars is 3.4 years. TheDepartment of Transportation would like to set a = 0.10. The conclusion for this hypothesis test would be that because the test statistic isQuestion options:A) more than the critical value, we can conclude that the average age of cars on the road is less than 10 years.B) more than the critical value, we cannot conclude that the average age of cars on the road is less than 10 years.C) less than the critical value, we can conclude that the average age of cars on the road is less than 10 years.10. YouTube would like to test the hypothesis that the average length of an online video watched by a user is more than 6 minutes. A random sample of 40people watched online videos that averaged 6.6 minutes in length. It is believed that the population standard deviation for the length of online videos is 1.7minutes. YouTube would like to set a = 0.05. Which one of the following statements is true?Question options:A) Because the p-value is greater than a, we reject the null hypothesis and conclude that the average length of an online video is more than 6 minutes.B)Because the p-value is greater than a, we fail to reject the null hypothesis and conclude that the average length of an online video is less than 6 minutes.C) Because the p-value is less than a, we fail to reject the null hypothesis and conclude that the average length of an online video is less than 6 minutes.D) Because the p-value is less than a, we reject the null hypothesis and conclude that the average length of an online video is more than 6 minutes.

A data set consists of the 11 data points shown below, plus one additional data point. When the additional point is included in the data set, the sample standard deviation of the 12 points is computed to be 15.225. If it is known that the additional data point is 25 or less, find the value of the twelfth data point. 48, 42, 12, 56, 33, 23, 24, 21, 37, 21, 27 Value of the additional data point =

The amounts of coffee dispensed into the cup are normally distributed with a standard deviation of 0.02 ounce.You can allow the cup to overfill at most 2% of the time. What is the greatest amount should you set as the mean amount of coffee to be dispensed? Round final answer to the third decimal place.
On average, Americans have lived in 4 places by the time they are 18 years old. Is this average a different number for college students? The 41 randomly selected college students who answered the survey question had lived in an average of 4.16 places by the time they were 18 years old.

Most people think that the "normal" adult body temperature is 98.6°F. In a more recent study, researchers reported that a more accurate figure may be 98.1°F. Furthermore, the standard deviation appeared to be around 0.7°F. Assume that a Normal model is appropriate. b) What fraction of people would be expected to have body temperatures above 98.6°F?
