Answer:
Step-by-step explanation:
If the youngest person leaves and is not replaced by another person, it means the mean age is no longer be 20.2 and the median is no longer is 19.
There are 4 students left, so
<u>Mean</u>: will inscrease, when number of terms descrease (only 4)
<u>Media</u>: will descrease, when we have to calculate the average value for term number 2 and 3, not only term number 3 before the youngest person leaves.
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
