For the following hypothesis test: With n = 80,σ = 9,and = 47.1,state the conclusion.
A)Because the computed value of z = 3.012 is greater than 2.05,accept the null hypothesis and conclude the mean is greater than 45.Also because the p-value is less than 0.02
B)Because the computed value of z = 3.012 is greater than 2.05,reject the null hypothesis and conclude the mean is greater than 45.Also because the p-value is less than 0.02
C)Because the computed value of z = 2.087 is greater than 2.05,accept the null hypothesis and conclude the mean is greater than 45.Also because the p-value is less than 0.02
D)Because the computed value of z = 2.087 is greater than 2.05,reject the null hypothesis and conclude the mean is greater than 45.Also because the p-value is less than 0.02
