In a roller-skating rink, the skaters all move at different speeds. most skate slightly faster or slower than others, but sometimes an adventuresome skater accelerates to an "outlying" speed that is much higher than that of everyone else, creating a hazard. as a result, skating rinks often post a sign that says: any skater moving faster than the average speed of all the skaterswill be asked to leave the rink. it is clear what the sign means, but it is statistically nonsensical. if there are 100 skaters in a rink, all skating at slightly varying speeds, what is the best estimate for how many of them are moving faster than the average speed of all the skaters?

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
