MY NOTES
ASK YOUR TEACHER
You may need to use the appropriate appendix table or technology to answer this question.
UHON Research Group has tested the hypotheses regarding the IQ of university honor students. They
provided the following information.
Ho: MS 144
H:> 144 (Genius)
Sample size n = 121
Sample size mean 1471
p-value 0.0059
(a) Using a = 0.015, would you reject or not reject the null hypothesis? Explain how you arrived at your
answer and what you can conclude about the IQ scores of UHON students?
We would reject
There is ---Select---
the null hypothesis because the p-value is ---Select---
evidence that the average IQ score of UHON students is above 144.
(b) The researchers failed to report the standard deviation. Determine the standard deviation. Use the
normal distribution table to answer this question. (Round your answer to three decimal places.)

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.
