Essay

Solve the problem.
-Various temperature measurements are recorded at different times for a particular city. The mean of $20 ^ { \circ } \mathrm { C }$ C is
obtained for 60 temperatures on 60 different days. Assuming that $\sigma = 1.5 ^ { \circ } \mathrm { C }$ test the claim that the population
mean is 22°C. Use a 0.05 significance level.
