For the data shown in the stem-and-leaf plot, what is the effect on the mean and median of adding the value 10 to the data set?
A. The mean is decreased by about 0.7 and the median is decreased by 2. B. The mean is decreased by about 0.7 and the median is decreased by 3. C. The mean is decreased by about 1.2 and the median is decreased by 2. D. The mean is decreased by about 1.2 and the median is decreased by 3.
The correct answer for the question that is being presented above is this one: "<span> C. The mean is decreased by about 1.2 and the median is decreased by 2." </span>For the data shown in the stem-and-leaf plot, the effect on the mean and median of adding the value 10 to the data set is that t<span>he mean is decreased by about 1.2 and the median is decreased by 2.</span>
Assuming the root sign is over both the numerator and denominator, find the square root of both numbers (6 and 11). The two answers are positive and negative 6/11 because multiplying two negatives makes a positive.
