Hi there!
With a normal distribution, we can use the operation 'normalcdf' on a calculator to find the probability that a randomly selected adult has an IQ between 96 and 111.
Here is the format for using the operation:
<h2>normalcdf(LB, UB, μ, σ) </h2>LB = Lower bound (96)
UB = Upper bound (111)
μ = Mean of normal distribution (100)
σ = Standard deviation of normal distribution (15)
Plug in the given values into the calculator and solve.
