Does it pay to ask for a raise? A national survey of heads of households showed the percentage of those who asked for a raise an
Vedmedyk [2.9K]

Answer: (a) 0.26 (26%)

               (b) 0.45 (45%)

                (c) 0.117 (11.7%)

Step-by-step explanation:

(a) P( woman asked for a raise ) = 0.26

This part is given in the question as 26% (The sample statistic). This is the proportion of women who asked for a raise.

(b) P(received raise given she asked)

This is a conditional probability question, as we are looking for the chance that a woman received a raise given she already asked for one.

P(received raise/asked for one) = P(received raise and asked for one) /  P(asked for one)

                                                    = (0.26 x 0.45) / 0.26

                                                    = 0.45

(c) P(asked for raise and received one)

This is a Joint probability and it is found by multiplying the the probability that she received a raise given she asked for one by the probability that she asked for one. This can be deduced by rearranging the conditional probability formula in (b) above.

  = P(received raise/ she asked for one ) x P(asked for one)

  =  0.45 x 0.26

  = 0.117
