According to YCharts in 2018, the unemployment rate for 15- to 24-year-olds in British Columbia was reported to be 9.4% for July, 2018 specifically. Suppose that this report was based on a random sample of four hundred 15- to 24-year-olds. A political campaign manager wants to know if the sample results can be used to conclude that the unemployment rate for 15- to 24-year-old British Columbians is significantly higher than the unemployment rate for all adults in British Columbia based on a significance level α=0.05 α=0.05. According to the Statistics Canada, the unemployment rate for all adults in British Columbia was 5.0% in July 2018. State the hypotheses. Calculate the test statistic. Use Excel to find the p-value. Hint: Use NORM.DIST. What is your hypothesis test decision? What is your conclusion in the context of the application?
