You just administered an opportunity for your students to demonstrate their understanding of placement values. Upon reviewing the results, you found that the average raw score was 28 (i.e., µx = cxplain what thcsc mcasurcs tcll you. 28) and the data had a standard deviation of 9.3 (i.e., ox=9.3). In a paragraph, %3D

Students in a class took a test whose results were normally distributed.  The mean score was an 81 and the standard deviation was 4.5.  What score is at the 83rd percentile (round to the nearest whole number.) a.84 b.83 c.85 d.86

Given the information provided, need help describing the type of association between Area and SpineL. Thank you :)

Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 Sample mean for Car 2 x= 245 mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.) times on each car and records the number of miles driven. Full data set Car 1 Median for Car 1 M= mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.) 245 242 215 244 220 265 291 160 284 251 169 319 257 306 267 Car 2 Median for Car 2 230 242 M=O mi / 10 gal 206 214 236 256 245 255 241 264 (Type an integer or decimal rounded to one decimal place as needed.) 276 252 250 251 257

In some reports, the mean and coefficient of variation are given. For instance, one report gives the average number of physician visits by males per year. The average reported is 2.6, and the reported coefficient of variation is 2.3%. Use this information to determine the standard deviation of the annual number of visits to physicians made by males. (Round your answer to three decimal places.)
