According to the Internal Revenue Service (IRS), the average length of time for an individual to complete the tax return form is 10.18 hours. The distribution of the length of time to complete tax return is unknown. Let us assume that the population standard deviation is 2 hours. Suppose we randomly sample 36 taxpayers. Find the probability that the 36 taxpayers took an average of more than 11 hours to finish their tax return. (Round your answer to four decimal places.)

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
