Pick the correct statements?

• A. 135
• B. 143
• C. 152
• D. 150

Answer 1

Answer: (A), (B)

The correct options are
A

135

B

143

We arrange the given data in the following way:

124, 132, 135, 143, 143, 143, 149, 150, 152 , 158 .

We see that in the above observation 143 is the height of the maximum number of students. Since the mode of a given number of observations is that value which occurs most frequently, the mode of the given data is 143.
Since there are 10 observations, the median is the average of the 5th and 6th observations
$Median=\frac{143+143}{2}$
