Answer:
a) 279 b)254
Step-by-step explanation:
Mean = 269 days
standard deviation = 8 days
let n be the pregnancy lenght.
using normal distribution formula
z = (n – mean)/ standard deviation
n = z * standard deviation + mean
Now, z values for the top 12% has to be found using a z table.
The top 12% means 88% of area under the curve. In this case z = 1,176
n = 1,176 * 8 + 269
n = 278.4 = 279
The bottom 3% means 97% of area under the curve. In this case z = -1,882
n = -1,882 * 8 + 269
n = 253.94 = 254
A police officer paid 10% of her income between 0 and 8,350: 0.10*8350=$835
<span>A police officer paid 15% of her income between 8350 and 33,950: 33,950-8,350=25,600⇒0.15*25,600=$3,840
</span>A police officer paid <span>25% of her income between 33,950 and 47,050: 47,050-33,950=13,100⇒0.25*13,100=$3,275
$835+$3,840+$3,275=$7,950
</span><span>The policy officer paid $7,950 in federal income tax.</span>
