A tourism organization wants to open up the entire state to tourists.They know that not everyone is drawn to hot, sunny beaches, so they wantto advertise the advantages of visiting other parts of the state. One of thefirst things they need to do is educate potential tourists about the weather.And part of that involves informing them about the average rainfall acrossthe state. Your task is to help the tourism organization figure out what theaverage rainfall in Florida is like.

The frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates. Use the frequency distribution to approximate the population mean and population standard deviation Compare these results to the actual mean µ = $1.667 and standard deviation o=$1.073. Click the icon to view the frequency distribution for the tax rates. The population mean is $ (Round to three decimal places as needed) The population standard deviation is $ (Round to three decimal places as needed.) Compare these results to the values found using the actual data. OA. The grouped values are both slightly larger. OB. The grouped values are both slightly smaller. OC.

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 39 beats per minute, the mean of the listed pulse rates is x overbar equals 77.0 beats per minute, and their standard deviation is sequals 21.2 beats per minute. a. What is the difference between the pulse rate of39 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of39 beats per minutes to a z score. d. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 39 beats per minute significant?
