<span>The fully covered premium amounts to $4,668. Next, we calculate the partially covered premium using:
25% * 9,264 = 2,316
Now, the total annual premium paid by Mr. Henderson's employer is equivalent to the sum of the completely covered premium and partially covered premium. This is:
4,668 + 2,316
= $6,984 of the Henderson family's annual premium is covered by Mr. Henderson's employer</span>
Answer:
The original cost is
$385
Step-by-step explanation:
Step one:
given data'
cost of bicycle= $138
helmet = $16
Total cost = 138+16= $154
Step two:
let the original cost be x
we are told that 40% of x= 154
hence
40/100*x= 154
0.4x=154
divide both sides by 0.4
x= 154/0.4
x=$385
The main difference can be directly observed in the
formulas used to calculate for the margin of error.
For the population mean, the margin of error would simply
be:
<span>MOE = z * s / sqrt(n)
where z is the z-score, s is the standard deviation and n is the number of
samples</span>
For the population proportion, the margin of error is:
MOE = z * sqrt[p (1 – p) / n]
<span>where p is the probability of success </span>
