Please help me provide an original word problem involving the normal curve concepts, with solution, steps, and conclusion thankyou, please see example below

PROBLEM SOLVING INVOLVING THE NORMAL CURVE CONCEPTS Example 1. The Intelligence Quotient (IQ) scores for people are normally distributed with a mean of 100 and a standard deviation of 16. If Bettina was randomly selected to take a test, what is the probability that her score is between 100 and 120? Step 1. Construct a normal curve and put the given values to understand the situation z score raw score 100 116 132 148 120 Step 2. Identify the corresponding z score of 100 and 120. 100 -> z = 0 7= - (Since 100 is the mean) 120-100 16 z = 1.25 120 -> z = 1.25 Step 3. Identify the proportion of the area corresponds between z = 0 and z = 1.25 z = 1.25 + 0.3944 Therefore Bettina probability that her score will fall between 100 and 120 is 0.3994 or 39.44%
