According to the Internal Revenue Service, the length of time for an individual to complete (learn, prepare copy, assemble, and send) IRS Form 1040 is normally distributed with a mean of 12.14 hours (without any attached schedules). Suppose the standard deviation is 1.5 hours. 1. If one taxpayer is randomly selected, what is the probability that they took more than 12.46 hours to complete form 1040? • What distribution will you use to calculate this probability? NO o List the z-scores needed to calculate the result. If there is more than one z-score, separate the values with a comma. chance that a randomly selected taxpayer took o There is a longer than 12.46 hours to complete their tax return. 2. If 95 taxpayers are randomly selected, what is the probability that, on average, they took more than 12.46 hours to complete form 1040? o What distribution will you use to calculate this probability? NO o List the z-scores needed to calculate the result. If there is more than one z-score, separate the values with a comma. chance that a random sample of 95 taxpayers took o There is a longer than 12.46 hours to complete their tax returns, on average.
