Question

On a planet far far away from Earth, IQ of the ruling species is normally distributed with a mean of 111 and a standard deviation of 15. Suppose one individual is randomly chosen. Let x = 10 of an individual. a. What is the distribution of X? b. Find the probability that a randomly selected person's over 125.Round your answer to 4 decimal places. C. A school offers special services for all children in the bottom 5% for scores. What is the highest score a child can have and still receive special services? Round your answer to 2 decimal places d. Find the Inter Quartile Range (10R) for scores. Round your answers to 2 decimal places. Q1 : 03 : IQR :

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Expert Solution

Step 1

Normal distribution is the continuous probability distribution with parameter mean $μ$ and variance $σ^{2}$ . The shape of the normal distribution is a bell-shaped curve. The total area under that curve is one.

If the normal distribution with mean=1, and S.D=0 then it is the Standard normal distribution.
