Answer:
The population proportion is estimated to be with 99% confidence within the interval (0.1238, 0.2012).
Step-by-step explanation:
The formula for estimating the population proportion by a confidence interval is given by:
Where:
is the sample's proportion of success, which in this case is the people that regularly lie during surveys,
is the critical value needed to find the tails of distribution related to the confidence level,
is the sample's size.
<u>First</u> we compute the value:
<u>Next</u> we find the z-score at any z-distribution table or app (in this case i've used StatKey):
Now we can replace in the formula with the obtained values to compute the confidence interval:
Answer:
$8016.00
Step-by-step explanation:
I = 6000 × 0.042 × 8 = 2016
I = $ 2,016.00
$2,016.00 + $6,000.00 = 8,016.00
Answer:
$33
Step-by-step explanation:
From the question, $22 is correct
If Helen Ming receives travel allowance of $220 from her company for time away from home
She has a 10% income tax rate
The amount she has to pay in taxes for the employee benefits is
10% of $220
10/100*$220
=0.1*$220
=$22
So you are correct
The only reason why you could be wrong is if the question is different from what you posted above just like the below question
Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable and she has a 15 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?
Here the amount she has to pay for the employee benefits is
15% of $220
15/100*$220
=0.15*$220
=$33
Answer: She would have to practice for 3/4 of an hour left to reach her goal
