Compute the value of the test statistic for testing H0: μ = 30 vs. Ha: μ > 30, based on the information σ = 2.53, n = 32, LaTeX: \bar{x}x ¯= 30.2, s = 2.58.
a) 2.536
b) 0.439
c) 2.488
d) 0.447
e) 0.089
Sol:
z=xbar-mu/sigma/sqrt(n)
xbar=30.2
sigma=2.53
n=32
mu=30
z=(30.2-30)/(2.53/sqrt(32)
z= 0.4471822
Z=0.447
ANSWER:
0.447
