Question

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars. Calculate the following. (Enter an exact number as an integer, fraction, or decimal.)

mode

Answer 1

Solution:

Given: Total  car salespersons selected in sample = N = 65

Fourteen people answered that they generally sell two cars;

nineteen generally sell three cars;

twelve generally sell four cars;

nine generally sell five cars;

eleven generally sell six cars.

Thus frequency distribution table is:

Number of Car sell	Number of car salespersons
2	14
3	19
4	12
5	9
6	11
	N = 65

We have to find the mode.

Mode is the random variable value whose frequency is maximum.

From above table maximum frequency is 19 and it corresponds to Number of Car sell = 3

Thus Mode = 3
