Question 2 (1 point) Population
C: 25 beetles are left in a bin, undisturbed, for 5 weeks. Each
week, the number of beetles is recorded. The equation P(x) =
25•2 models the number of beetles, P(x), after x weeks.
1) Calculate the average rate of change between Weeks 1 & 3
2) Calculate the average rate of change between Weeks 0 & 5
3) Between which pair of weeks, 1-3 or 0-5, is the average
rate of change greatest? Why do you think this is the case?

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
