A house cleaning service claims that it can clean a four-bedroom house in less than 2 hours. A sample of n = 36 houses is taken and the sample mean is found to be 1.97 hours and the sample standard deviation is found to be 0.1 hours. Using a 0.05 level of significance the correct conclusion is: a) b) c) d) Question 8 options: Do not reject the null because the test statistic (-1.8) is > the critical value (- 1.96). Reject the null because the test statistic (-1.8) is > the critical value (-1.96). Do not reject the null because the test statistic (-1.8) is < the critical value (- 1.64). Reject the null because the test statistic (-1.8) is < the critical value (-1.64).

Question

A house cleaning service claims that it can clean a four-bedroom house in less than 2 hours. A sample of n = 36 houses is taken and the sample mean is found to be 1.97 hours and the sample standard deviation is found to be 0.1 hours. Using a 0.05 level of significance the correct conclusion is: a) b) c) d)

Question 8 options:

	Do not reject the null because the test statistic (-1.8) is > the critical value (- 1.96).
	Reject the null because the test statistic (-1.8) is > the critical value (-1.96).
	Do not reject the null because the test statistic (-1.8) is < the critical value (- 1.64).
	Reject the null because the test statistic (-1.8) is < the critical value (-1.64).
