In April of 2011, the unemployment rate in Canada was reported to be 7.7%. Suppose that Statisties Canada claims that the current unemployment rate is lower than that of April 2011. Suppose a test was conducted on current unemployment and a random sample size of 1200 found an unemployment rate at 6.8%. Test an appropriate hypothesis and state your conclusion. Use a significance level of 10.0%. (a) What are the null and alternative hypotheses? = 0.077 : =: 0.077 : Ho: P HA: P (b) What is the test statistic? (Round your answer to 2 decimal places, if needed.) (c) Using the statistical table, what is the p-value? (Round your answer to 4 decimal places, if needed.) (d) Based on the p-value, fail to reject + the null hypothesis. (e) This data does not provide + sufficient evidence to conclude that the unemployment rate has decreased since April of 2011.

unemployment rate is lower than that of April 2011. Suppose a test was conducted on current unemployment and a random sample size of
1200 found an unemployment rate at 6.8%. Test an appropriate hypothesis and state your conclusion. Use a significance level of 10.0%.
