For a recent season in college football, the total number of rushing yards for that season is recorded for each running back. The mean number of rushing yards for the running backs that season is 790 yards. One running back had 1,637 rushing yards for the season, which is 2.42 standard deviations above the mean number of rushing yards. What is the standard deviation of the number of rushing yards for the running backs that season?
Accepted Solution
A:
Answer:(C) 350 yardsStep-by-step explanation:From available informationMean = 7901 running back = 1637 yardsStandard deviation above mean = 2.42Using formulaz =( x - mean)/sd2.42 = (1637-790)/sd2.42 = 847/sdWe cross multiply2.42sd = 847Divide through by 2.42Sd = 847/2.42Sd = standard deviation = 350So our answer is 350 and therefore option c.
