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.
Answer:
-0.83 <√4 <2.63 <√8
Step-by-step explanation:
We need to place the numbers √4, 2.63, √8, and-.83 in order from least to greatest.
We know that,
√4 = 2, √8 = 2.82
A number line starts from negative no then 0 and finally positive numbers.
The smallest no is negative no i.e. -0.83 and the greatest no is √8 i.e. 2.82
The sequence from least to greatest is :
-0.83 <√4 <2.63 <√8
