Suppose a recent plant journal indicated that the mean height of mature plants of a certain species of sunflower is 10.4 ft. A
biologist observing a huge field of mature plants of this particular species of sunflower thinks that the mean height is shorter
than reported. He measures the heights of 45 randomly selected sunflowers and finds the mean height to be 10.1 ft.
The hypotheses of interest are :
(A) H0 : µ = 10.1 vs Ha : µ < 10.1
(B) H0 : µ > 10.4 vs Ha : µ = 10.4
(C) H0 : ¯x = 10.1 vs Ha : ¯x > 10.1
(D) H0 : ¯x = 10.1 vs Ha : ¯x < 10.1
(E) H0 : µ = 10.4 vs Ha : µ < 10.4
