The data set represents the total number of tickets each person purchased for a play. 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 what is the median of the data? 1 1.5 2 2.5

 Median for given observations is  1.5

Explanation:

We have two formulas to find median

Case 1: when number of observations is even  we find median as below

taking average of and

Case 2: when number of observations is odd we find the

Here we have total  10 number of observations so this falls in the category of Case 1 which is for even terms.

we have to take the average of   term  and term

Here n = 10 so substituting the value of n = 10 in the formula we will get

So, taking the average of term means taking numbers at position that is 1 and 2

It will gives =1.5

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

answer: 0.64
