Question

(8) There are 10 observations arranged in ascending order as given below.

45,47,50,52, x, x +2,60,62,63,74

The median of these observations is 53.Find the value of x Also find the mean and the mode of the data.​

Answer 1

Step-by-step explanation:

n=10(even)

median=½{(n/2)th observation+(n/2+1)th observation}

=½{5th observation+6th observation}

=½(x+x+2)=53

2x+2= 53×2

2x=106-2

x=104/2

x=52

then fine mean and mode by their formula
