We are interested in knowing if the following frequency distribution is normally distributed. The mean and standard deviation of the data is 600 and 160. To test the hypothesis that the frequency distribution is normally distributed, what is the value of the chi-square critical value at the .05 level of significance?

Standard Deviation

A measure of the dispersion or variability within a set of numerical data, indicating how much individual data points differ from the mean.

Mean

The mean of a set of numbers obtained by summing them up and then dividing by the total number of values.
