A = 80/2 = 40
b = 100/2 = 50

d = 180 - (a+b)
d = 180 - (40+50)
d = 180 - 90
d = 90

To work out the median, you need to numerically sort the data (because currently, it's unordered).

The ordered set of data is: 22, 38, 44, 59, 70, 79, 85, 87, 96

Now you just need to pick the middle value, which is 70:

(as you can see: 22, 38, 44, 59, 70, 79, 85, 87, 96)

Therefore, your answer is 70 :)

From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;

- Yes, the sampling method is biased.

- The likely direction of the bias is because you only asked 5 people which

is not a significant percentage of those offering psychology majors and as

such the 4 out of 5 gotten is likely going to be an over estimation of those

who are willing to pay to join this club.

We are told that;

You want to find the proportion of those in the psychology majors that will join this club you want to organize.

Now, out of all the students offering psychology majors, you only asked 5 of them if they will be interested. Since 4 out of the 5 are interested and you want to use that to form a basis of the proportion of those interested , it would lead to sampling bias since the population is not adequately represented.

Therefore, this would lead to sampling bias and thus the sample is biased.
