A policeman records the speeds of cars on a certain section of roadway with a radar gun. The histogram below shows the distribution of speeds for 251 cars. The maximum value is 35 mph. 60- 50 40 30- 20 10 0 20 22 24 26 28 30 32 34 Speed (mph) If the value, 35 mph, was actually 29 mph, how would the mean and standard deviation change? O the mean would decrease and the standard deviation would decrease O the mean would stay nearly the same and the standard deviation would increase O the mean would increase and the standard deviation would increase O the mean would stay nearly the same and the standard deviation would stay nearly the same O the mean would stay nearly the same and the standard deviation would decrease 36 & 1. 2 目首 E [] <
