2.5?Hypothesis Testing?Suppose we have a setof sample data {X1, X2, …, X 10} from a normal distribution with mean μ and variance 2 . We want to use the t statistic to test whether the sample mean is equal to a certain value μ=5. Now we construct the null hypothesis and aitemative hypothesis:Null hypothesis Ho: μ=5Alternative hypothesis H 1: μ≠ 5It is known that this set of sample data is (4,8,5,1,5,3,4,9,5,2,5,0,4.7,5,4,5,1,4,9). Based on the sample mean and sample standard deviation, calculate
