Question 1168893: Assume that the average number of miles driven each week by drug dealers in Southern California follows an approximate normal distribution, with the population mean equal to 95 and the standard deviation equal to 8. Answer the following:
12. What percentage of dealers drive more than 112 miles each week? I GOT 98.34% AM I CORRECT?
13. What percentage of dealers drive between 90 and 110 miles each week? I need help solving this question
14. What percentage of dealers drive either less than 86 miles per week or more than 102 miles per week? I GOT 12.92% AM I CORRECT?
You can put this solution on YOUR website! 12. It is the complement or 1.68% (little different with no rounding until end)--draw the distribution and note that more than 112 miles a week is small. Drawing helps you estimate what the answer should or should not be.
13. Between 90 and 100 is between -5/8 sd and +5/8 sd
or 0.4680 probability.
14. 32.11% probability
fewer than 86 miles is <-1.125 sd or 0.1303 probability
more than 102 miles is z>0.875 or 0.1908 probability
