Using the data obtained in Exercise 5, test the hypothesis H 0 : 150. Use = 0.05. Assume the variable is normally

Using the data obtained in Exercise 5, test the hypothesis H₀ : σ ≥ 150. Use α = 0.05. Assume the variable is normally distributed.

Data From in Exercise 5

Using the data from Data Set XIII, select a sample of 10 hospitals, and test H₀ : µ = 250 and H₁ : µ
