B. Test statistic z=-10.23. There is sufficient evidence to warrant rejection of the claim that the population mean temperature is 22 degree C.
C. Test statistic z=-8.43. There is not sufficient evidence to warrant rejection of the claim that the population mean temperature is 22 degree C.
D. Test statistic z=-10.23. There is not sufficient evidence to warrant rejection of the claim that the population mean temperature is 22 degree C.

Various temperature measurements are recorded at different times for a particular city. The mean of 20 degree C is obtained for 40 temperatures on 40 different days. Assuming that \sigma=1.5 degree C,find the test statistic and test the claim that the population mean is 22 degree C. Use a 0.05 significance level.
Let 20.05 1.65, 20.025 =1.96
