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
Answer:
z=12
Step-by-step explanation:
divide by 1/2 to get the variable z by itself
Answer:
Revenue = Members * (Cost Per Member)
R = (12.500 *8) =
R= 100.000
R = (12.500 - 500) ( 8 + 1)=
R=12000*9=
R=108.000
Step-by-step explanation:
Revenue = Members * (Cost Per Member)
R = (12.500 *8) =
R= 100.000
R = (12.500 - 500) ( 8 + 1)=
R=12000*9=
R=108.000
