IM GIVING TO THE RIGHT COMMENT OR ANSWER A data set is made up of the values 2, 3, 7, 8, 9, and 13. The table shows the distance between each value and the mean of 7. Data value Distance between value and mean 2 5 3 4 7 0 8 1 9 2 13 6 Sum of distances 18 What is the mean absolute deviation (MAD) of the data set?

Which expression is equivalent to 2x^2+7x+4?

Which is f(5) for the function –2x2 + 2x - 3?

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
