The illustration below shows the graph of y as a function of 2.
Complete the following sentences based on the graph of the function.
(Enter the 2-intercepts from least to greatest.)
. This is the graph of a
y
function.
The y-intercept of the graph is the function value y =
• The x-intercepts of the graph (in order from least to greatest) are located at 2 =
and 2 =
• The greatest value of y is y = , and it occurs when 2 =
. For between c = 0 and x = 6, the function value y

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
