Question

Find the value of x the mode is 7 the following data 4,8,7,4,4,7,7,9,2x-5

Answer 1

Answer:

The given data has two observations which occurs maximum 3 times. These two observations are 4 and 7. Since it is given that the mode is 7, hence the value of the expression 2x -5 should give the result 7, which will increase the count of 7 to 4 times making the mode

Hence 2x-5 =7

2x=12

x=6
