6. [-/5.3 Points] DETAILS BBUNDERSTAT12 10.2.005.S. MY NOTES ASK YOUR TEACHER The age distribution of the Canadian population and the age distribution of a random sample of 455 residents in the Indian community of a village are shown below. Observed Number Age (years) Percent of Canadian Population in the Village Under 5 7.2% 47 5 to 14 13.6% 70 15 to 64 67.1% 298 65 and older 12.1% 40 LA USE SALT Use a 5% level of significance to test the claim that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village (a) What is the level of significance? State the null and alternate hypotheses. O Ho: The distributions are the same. H : The distributions are different. O Ho: The distributions are the same. H : The distributions are the same. O Ho: The distributions are different. H : The distributions are different. O Ho: The distributions are different. H : The distributions are the same. (b) Find the value of the chi-square statistic for the sample. (Round your answer to three decimal places.) Are all the expected frequencies greater than 5? O Yes O No What sampling distribution will you use? O binomial O normal O chi-square O Student's t O uniform e the degrees of freedom?(c) Estimate the P-value of the sample test statistic. O P-value > 0.100 O 0.050 a, we fail to reject the null hypothesis. O Since the P-value > a, we reject the null hypothesis. O Since the P-value s a, we reject the null hypothesis. O Since the P-value s a, we fail to reject the null hypothesis. (e) Interpret your conclusion in the context of the application. O At the 5% level of significance, the evidence is insufficient to conclude that the village population does not fit the general Canadian population. O At the 5% level of significance, the evidence is sufficient to conclude that the village population does not fit the general Canadian population
