If you vandalize my property I will call the cops.
E=Z*sqrt (p(1-p)/N), where E= error margin, p=proportion, N=sample size
Katrina's margin error at 85% confidence interval: E=1.96*sqrt (p(1-p)/100) = 0.196 sqrt (1(1-p))
Mathew's margin error at 99% confidence interval: E= 2.58*sqrt (p(1-p)/400) = 0.129 sqrt (p(1-p))
Since both obtained same estimate of proportion (that is, value of p), it can be seen that Mathew's estimate will have a small error (That is, 0.129 is smaller than 0.196). This can be attributed to larger sample size although a wider confidence (99%) interval was considered.
22+26+28+30+39+44+62+63= 314
Divide the answer by the amount of numbers
=39.25
Answer:
Hope this helps
Step-by-step explanation:
1/4x = -22 + 18
1/4x = -4
4(1/4x) = 4(-4)
x = -16
Answer:
Approximately 6 buses
Step-by-step explanation:
If you are wanting know how many vans they are going to need:
26 + 32 -This helps you know how many total kids there are
= 58
58 / 10 -This solves how many buses you'll need
= 5.8 - Round up, and say you need 6 buses.
