Find test statistic and p-value and make conclusion for
MEAN:
x=35, n=200, Ho: p=25%, H1: p<25%, confidence
level=0.05
Then find test statistic and p-value and make conclusion
for PROPORTION:
x̄=37, s=10.2, n=30, Ho: μ=32, H1: μ≠32,
confidence level=0.01
Now find test statistic and p-value and make conclusion
for TWO PROPORTIONS:
x1 = 6, n1 = 315, x2 = 80,
n2 = 320, Ho: p1 = p2,
HA: p1 < p2, α = 0.1
