What is the mean for Doctor A’s data set on corrective lenses? What is the mean for Doctor B’s data set on corrective lenses? Wr

Nat2105 [25]

Answer: Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

Step-by-step explanation:

To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.

Doctor A's mean:

Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.

Doctor B's mean:

Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2

Difference:

755.2-751.6 = 3.6
