The answer is 8and 10 when you divided is 0.8
Answer:
<h3>73220±566.72</h3>
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = xbar ± z*s/√n
xbar is the sample mean = $73,220
z is the z score at 99% CI = 2.576
s is the standard deviation = $4400
n is the sample size = 400
Substitute the given values into the formula;
CI = 73,220 ± 2.576*4400/√400
CI = 73,220 ± 2.576*4400/20
CI = 73,220± (2.576*220)
CI = 73220±566.72
Hence a 99% confidence interval for μ is 73220±566.72
Probably C)
it starts with 8-foot diameter, and it is supposed to get smaller
This is just a theory
Exact Form: 21/25
Decimal Form: 0.84
Step-by-step explanation: Reduce the expression, if possible, by cancelling the common factors.
