Question

On a separate piece of paper do the following hypothesis test and upload a picture or pdf of your work.

According to the norms established for a reading comprehension test, the scores of fifth graders should be normally distributed with a population mean of 81.4 and a population standard deviation of 8.4. A teacher believes her class of 35 students have a reading comprehension different than the norm and decides to give her class the test. The class average on the test was 79.5. Are these students different than the norm in their reading comprehension? Test at α = 0.01. Show all steps to receive full credit.

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.
