Considered numbers (strings) of length 8 over the 10 digits 0, 1, 2...,9 . Suppose that the repetition of the digits is allowed and that the numbers may begin with 0.
(a) how many different numbers are there?
(b) how many of these numbers contain at least two 2s?
(c) what is the probability that a string of length 8 will contain at least two 2s? ā

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 Ć®Å(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference Ć®Å(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference Ć®Å(x - x)2 by more than data sets (ii) and (iii). none of the above
