We have been given that adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketball player is 79 inches tall.
We need to find the area of normal curve above the raw score 79.
First of all let us find the z-score corresponding to our given raw score.
, where,
,
,
,
.
Upon substituting our given values in z-score formula we will get,
Now we will find the P(z>3) using formula:
Using normal distribution table we will get,
Let us convert our answer into percentage by multiplying 0.00135 by 100.
Therefore, approximately 0.135% of the adult male population is taller than the average basketball player and option A is the correct choice.
Your answer is going to be c
Slope formula
y2-y1/x2-x1
1 = x1
-7 = y1
3 = x2
-21 = y2
Plug in the given values into their corresponding spot in the formula:
-21 - (-7) / 3 - 1
-21 - (-7) is the same as -21 + 7
-21 + 7 is the same as 7 - 21
7 - 21 = -14
3 - 1 = 2
-14/2
-14 divided by 2 = -7
The slope is -7
