HELP PLEASE!!! The expected value of a random variable X is 35. The variable is transformed

Sunny_sXe [5.5K]

Answer:

Expected value x= 35

linear transformation is defined as a + bx

here, b=4, a=1

The transformation is $z=1+4x$

now, expected value, $l_z=l_z(a+bx)$

$=l(a)+l(bx)$

$=a+b\:l\:x$

substitute the value of a=1, b=4 and l=35

$l_z=1+4\times35$

$=1+140$

$=141$

So, the expected value of the transformed variable is <u>141</u>.
