Score: 0 of 1 pt 6 of 7 (3 complete) HW Score: 42.86%, 3 of 7 pts 3.4.25 Question Help The following data represent the monthly phone use, in minutes, of a customer enrolled in a fraud prevention program for the 504450 497 316D past 20 months. The phone company decides to use the upper fence as the cutoff point for the number of minutes at which the 416 453 388 545 customer should be contacted. What is the cutoff point? 324 345 438 405 308 329 360 389 474 394 458 480 The cutoff point is minutes. (Round to the nearest minute.)

Explanation / Answer

For the given data: First quartile, Q1= (345+360)/2 = 352.5

Third quartile, Q3 = (458+474)/2 = 466

Interquartile range,IQR = Q3 - Q1 = 113.5

Now, upper fence = Q3 + (1.5 × IQR) = 466 + (1.5 × 113.5) = 636.25

Thus, the cutoff point is 636 minutes
