The true average diameter of ball bearings of a certain type is supposed to be 0.5 in. A one-sample t test will be carried out to see whether this is the case. What conclusion is appropriate in each of the following situations? n = 16, t = 1.5, š¼ = 0.05
Added by Craig R.
Step 1
- Null hypothesis (H0): The true average diameter of the ball bearings is 0.5 in (Ī¼ = 0.5). - Alternative hypothesis (H1): The true average diameter of the ball bearings is not 0.5 in (Ī¼ ā 0.5). Show moreā¦

The true average diameter of ball bearings of a certain type is supposed to be .5 in. A one-sample t test will be carried out to see whether this is the case. What conclusion appropriate in each of the following situations? a. n = 13, t = 1.6, Ī± = .05 b. n = 13, t = -1.6, Ī± = .05 c. n = 25, t = -2.6, Ī± = .01 d. n = 25, t = -3.9

The true average diameter of ball bearings of a certain type is supposed to be 0.5 in. A one-sample t-test will be carried out to see whether this is the case. What conclusion is appropriate in each of the following situations? (a) n = 13, t = 1.6, Ī± = 0.05. (b) n = 13, t = -1.6, Ī± = 0.05. (c) n = 25, t = -2.6, Ī± = 0.01. (d) n = 25, t = -3.9, Ī± = 0.01.
