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:
Step-by-step explanation:
Given
Required
Find V, when s = 350
Substitute 350 for s in
Take:
So, we have:
--- approximated
A squared +b squared =c squared
so 24x24=576
18x18=324
576+324=900
square root of 900=30
the diagonol is 30
