A particular IQ test is standardized to a Normal model, with a mean of 100 and a standard deviation of 18. Using the empirical rule, about what percent of people should have IQ scores above 118? A 5% B 0.3% C 16% D 2.5%

Option C) 16%        

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100

Standard Deviation, σ = 18

We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.

Empirical Formula:

We have to find the percentage of data above 118.

From empirical rule we can write:

Thus, the correct answer is

Option C) 16%

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
