Answer:
Test statistic = 1.664
Step-by-step explanation:
The hypothesis :
H0 : μ = 47.2
H1 : μ ≠ 47.2
Given that :
Sample mean, xbar = 47
Sample size, n = 250
Standard deviation, σ = 1.9
The test statistic :
(xbar - μ) ÷ (σ/√(n))
T = (47 - 47.2) ÷ (1.9/√(250))
T = (0.2 / 0.1201665)
Test statistic = 1.664
Answer: 2
Step-by-step explanation:
A full rotation is 360 degrees, divide 360 by the rotation given in the problem:
360 / 120 = 3
A triangle has 3 inside angles, so the answer would be an equilateral triangle.
