Consider that a data set of 10 data points has a mean of 5. If every data point was doubled in the set, how might that affect the mean of the data set?

a) The mean would double to 10.

b) The mean would increase by 2 to 7

c) The mean would increase by 50.

d) The mean would remain to be 5.

What signals you that factoring by grouping is the best method to use when factoring a problem?

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100
