Fill in the missing values in the following table indicating the expected frequencies in each category for a sample size of 1,568, if the null hypothesis is true: Expected Frequencies Age Group Over 65 years 45-65 years 25-44 years 15-24 years Under 15 years 473.85 218.42 335.71 The chi-square statistic has been calculated for you: = 92.52. The distribution of the chi-square statistic has degrees of freedom. Use the following Distributions tool to find the critical value. With the level of significance = 0.05, the critical value is . Because the chi-square statistic is the critical value, you the null hypothesis. Therefore, you conclude that the proportions of people who are left-handed in the five age categories differ from the corresponding proportions for the total US population
