Compare the results from part (a) to this 90% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.169According to the Internal Revenue Service, income tax returns one year averaged $1,332 in refunds for taxpayers. One explanation of this figure is that taxpayers would rather have the government keep back too much money during the year than to owe it money at the end of the year. Suppose the average amount of tax at the end of a year is a refund of $1,332, with a standard deviation of $725. Assume that amounts owed or due on tax returns are normally distributed.(a) What proportion of tax returns show a refund greater than $2,400?(b) What proportion of the tax returns show that the taxpayer owes money to the government?(c) What proportion of the tax returns show a refund between $110 and $710?(Round the values of z to 2 decimal places, e.g. 2.53. Round your answers to 4 decimal places, e.g. 0.2531.) (a) P(x > $2,400) = enter proportion rounded to 4 decimal places(b) P(x < 0) = enter proportion rounded to 4 decimal places (c) P($110 ≤ x ≤ $710) = enter proportion rounded to 4…In a study of the accuracy of fast food drive-through orders, Restaurant A had 233 accurate orders and 66 that were not accurate. a.
