Question

117. If the range of a set of observations on
a variable X is known to be 25 and if
Y= 40 + 3X, then what is the range of
the set of corresponding observations
B1
on Y?
(a) 25
(6) 40
(©) 75
(d) 115
TCT in the variance and M is the magn​

Answer 1

Step-by-step explanation:

answer is 115 hope it helps you

Answer 2

Option 'd' is correct.

Step-by-step explanation:

Since  we have given that

X = 25

And

$Y=40+3X$

When we put the value of X in the above equation, we get that

$Y=40+3(25)\\\\Y=40+75\\\\Y=115$

Hence, Option 'd' is correct.
