An Excel assignment counts for 0-10 points. The scores in a class of 12 students are recorded as follows:1 5 5 6 7 7 8 8 8 9 10 10 What is the deviation of the score 10 from the mean in 13a (recall that this involves a subtraction of the mean from the particular score)? I think I got answer but want to check.
In Statsville there’s a city-wide speed limit of 30 mph.If you are caught speeding the fine is $100 plus $10 forevery mile per hour you were over the speed limit. Forexample, if you’re ticketed for going 45 mph, your fine is100 + 10145 - 302 = +250. Last month all the driverswho were fined for speeding averaged 42 mph with astandard deviation of 7 mph.
