Answer 2

Answer:

data:

11,15,17,(X+1),19,(x-2),3

sum of observation = 11+15+17+X+1+19+x-2+3

64+2x

number of observations= 7

therefore, mean = sum of observation/number of observations

14 = (64+2x)/7

64+2x = 14*7

64+2x = 98

2x = 98-64

X = 34/2

X= 17

therefore,

X+1 = 17+1 = 18

x-2 = 17-2 = 15

the data can be represented as:-

11,15,17,18,19,15,3.

so, mode is 15.

Step-by-step explanation:

don't get confused see the solution with full attention step by step so you would understand.

also here the mode is 15 because it's more then one time otherwise it would be 18 the middle number.
