Heights of Chihuahuas in a certain are normally distributed with a mean of 7.5 inches and a standard deviation 1.5 inches. If a group of 12 Chihuahuas is selected, find the probability that their mean height is shorter than 7 inches. Graphing Calculator Function:  [method] Conclusion:  [conclusion]  

Billy Joe’s Ice Cream store is interested how the weather affects their ice cream sales. The following table represents data from randomly selected spring, summer, and fall months over a few years. The number of days in the month with no cloud cover and the numbers of ice cream cones sold for that month were recorded. Determine if there is a linear correlation between the number of days with no cloud cover and the number of ice cream cones sold. Graphing Calculator Function:  [method] Is there significant linear correlation?  Yes or No? [correlation]   Using the data above, find the regression line, and preict the number of cones sold when a month has 13 days with no cloud cover. Regression Line:  [equation] Number of cones sold:  [sold]

A soft drink filling machine fills bottles that are supposed to have a mean volume of 20 ounces. A prospective buyer suspects that this is incorrect and customers are being cheated because the mean volume is actually less than 20 ounces. The volumes for a random sample of bottles are listed below. At the 0.05 significance level, test the buyer’s claim. What would you tell the buyer? 19.2    21.2    19.1    18.2    18.8    20.9    20.1    17.2    18.1    20.0    17.2    18.0    17.6 Graphing Calculator Function:  [method] Conclusion:  [conclusion]
