According to the Internal Revenue Service, the average length of time for an individual to complete (keep records for, learn, prepare, copy, assemble, and send) IRS Form 1040 is 10.41 hours (without any attached schedules). The distribution is unknown. Let us assume that the standard deviation is two hours. Suppose we randomly sample 36 taxpayers.

A) In words, define the random variable X.

the length of time, in minutes, for an individual to complete IRS Form 1040the length of time, in hours, for an individual to complete IRS Form 1040    the number of individuals who complete IRS Form 1040the number of taxpayers sampled

B) In words, define the random variable

X.

the average length of time, in hours, for a sample of 36 taxpayers to complete IRS Form 1040the average income of a random sample of taxpayers    the average length of time, in minutes, for a sample of 36 taxpayers to complete IRS Form 1040the average length of time, in hours, for a sample of 100 taxpayers to complete IRS Form 1040

c)

Give the distribution of

X.

(Round your answers to two decimal places.)

X ~

D) Find the probability that the 36 taxpayers took an average of more than 12 hours to finish their Form 1040s. (Round your answer to four decimal places.)

E) Would you be surprised if the 36 taxpayers finished their Form 1040s in an average of more than 12 hours? Explain why or why not in a complete sentence.

No, because the probability is very close to 1.Yes, because the probability is very close to 0.   

To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3700, and the average first-year commission for each new account opened is $5300. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. Assume that the number of new accounts you get randomly is: Simulation Trial New Accounts :

Construct a spreadsheet simulation model to analyze the profitability of Gustin’s seminars. Round the answer for the expected profit to the nearest dollar. Round the answer for the probability of a loss to 2 decimal places. Enter minus sign for negative values. The expected profit from a seminar is ______$ and there is a probability of a_______loss. Would you recommend that Gustin continue running the seminars? . How large of an audience does Gustin need before a seminar’s expected profit is greater than zero? Use Trial-and-error method to answer the question. Round your answer to the nearest whole number. ______attendees
