Question

Stats help please?

Answer 1

@kropot72 could you help me with this please?

Answer 2

You need to plug the given value of x (x = 8) into the given equation, which is as follows:
\[\large \ln (y)=7.55-0.556x\]
Then calculate the value of y.

Answer 3

ohhh thanks! so i do: 7.55- 0.556(8)= 7.55-4.448=3.102 ?

Answer 4

You are correct so far. The equation is now reduced to:
\[\large \ln (y)=3.102\]
Now you need to find the value of y.

Answer 5

ohh ok thanks, so do i divide both sides by ln?

Answer 6

Not really. The equation we now have says that the natural logarithm of y is 3.102. We can therefore write:
\[\large y=e^{3.102}\]
So now you need to use a calculator to find the value of the exponential number e raised to the power of 3.102.

Answer 7

i got 22.242

Answer 8

Good work! That is correct.

Answer 9
