The U.S. National Center for Health Statistics publishes data on weights and heights by age and sex in Vital and Health Statistics. The following (sorted) weights, to the nearest tenth of a pound, were obtained from a sample of 18-24-year-old males: 129. 2, 129. 3, 147, 150. 1, 151. 9, 154. 4, 155. 8, 156. 5, 158. 1, 160. 5, 160. 7, 162, 169.7, 169.8, 173.3, 174. 6, 178. 4, 180. 7, 185, 189. 5, 214. 5, 215. 6, 217. 6, 218. 9, 219.4.

The British Department of Transportation studied to see if people avoid driving on Friday the 13th. They did a traffic count on a Friday and then again on a Friday the 13th at the same two locations. The data for each location on the two different dates is in the table. Estimate the mean difference in traffic count between the 6th and the 13th using a 95% level. Round to the nearest whole number. Traffic Count Dates 1990, July 1990, July 6th 13th 124843 122766 122384 122909 1991, September 124255 122340 1991, September 123125 120366 1991, December 1991, December 127873 128871 118840 115788 135754 133695 1992, March 1992, March 131116 128582 1992, November 133042 130642 1992, November 126159 127110 With 95 count between the 6th and the 13th is between O % confidence, it can be said that the true mean difference in traffic and

From the following set of data, find the mean, median, mode, range and sample standard deviation. 45, 62, 23, 50, 76, 50, 99, 72, 51, 80

The following data represent the miles per gallon for a particular make and model car for six randomly selected vehicles. Compute the​ mean, median, and mode miles per gallon.   30.8​, 27.7​, 26.3​, 31.7​, 39.5​, 23.4    Compute the mean miles per gallon. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.     A. The mean mileage per gallon is nothing. ​(Round to two decimal places as​ needed.)   B. The mean does not exist.

An employment agency claims that the mean annual pay for full-time male workers over age 25 and without high school diplomas is $24,600. The annual pay for 10 full-time male workers over age 25 and without high school diplomas is shown below. $22,954 $23,438 $24,655 $23,695 $25,275 $19,212 $21,456 $25,493 $26,480 $28,585 Assume the distribution of the population is approximately normal. The P-value is as.12) (Round answer to two decimal places. Do not write 0.12

Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. The January 1990 issue of Arizona Trend contains a supplement describing 12 "best" golf courses in the state. The yardages (lengths) of these courses are as follows: 6981, 7099, 6930, 6992, 7518, 7100, 6935, 7518, 7013, 6800, 7047, and 6892. Calculate the sample mean and sample standard deviation. Round your answers to 1 decimal place. Sample mean =  Sample standard deviation =
