A local council official wishes to test the hypothesis that the average hourly wage of council office cleaners is the National Living Wage of £8.72 against the alternative hypothesis that it is higher than this value. A random sample of 16 cleaners provides a sample mean hourly wage of £9.00 with a sample variance of 4.00.

Under the assumption that the target population is normally distributed, The
critical value used to conduct the test, using a 5% significance level is (to two
decimal places):

		1.75
		1.96
		2.13
		None of the other answers is correct
