3. Using the file lab3b-sample.txt, create frequency tables (showing both frequency and relative frequency) to summarize the distribution of income groups for houscholds in Edmonton. (d) Carry out an appropriate hypothesis test at a = 0.05 to see whether the proportion of houscholds in Edmonton with income under $50,000 is now higher than 22.92% (which is the rounded percentage of households with income under $50,000 in the 2016 census). State the null and alternative hypotheses. Report the value of the appropriate test statistic, the distribution of the test statistic under the null hypothesis, and the P-value of the test to answer the question. State your conclusion.
