Answer:
Step-by-step explanation:
a)
zo=(89.0-92.2)/sqrt((1.5/15)+(1.2/20))
zo=-8.00
p-value=0.0000
Reject the null hypothesis.
b)
95% confidence interval for difference
=(89-92.2)+/-1.96*sqrt((1.5/15)+(1.2/20))
=-3.2+/-0.78
=(-3.98, -2.42)

Answer:
SA = 384 in ^2
Step-by-step explanation:
The surface area of a cube is given by
SA = 6 S ^2 where s is the side length
SA = 6 * (8) ^2
SA = 6 * 64
SA = 384 in ^2
