Question

if b=1.5,r=0.8 and standard deviation of X is 1.6 find the standard deviation of Y​

Answer 1

Answer:

this is your caract answer

Answer 2

Answer:

The standard deviation in y is = 3

Step-by-step explanation:

As it is known to us that
$b=r*\fracs_ys_x$

In the question it is given to us that b=1.5 r=0.8 and $S_x$ = 1.6, Putting these values in formula we get
$1.5=0.8*\frac {S_y}{1.6}\\S_y=3$

Hence standard deviation in y is = 3
