The cost of 5 gallons of ice cream has a standard deviation of 8 dollars with a mean of 33 dollars during the summer. What is the probability that the sample mean would differ from the true mean by less than $1.3$ dollars if a sample of 183 5-gallon pails is randomly selected? Round your answer to four decimal places. SP.SS. 397

Employees of KB and SONS Consultants Limited are paid at an hourly basics of 25GHS per an hour for regular hours and 1.5 times per hour for overtime hours in a week. Any hour worked over 40 hours per week is overtime. The following national tax sliding scale is then applied to determine the amount of tax to be paid by an employee. GrossWage Tax Rate (%) First 125 0 Next 125 5 Next 1500 10 Next 2750 15 Next 1250 20 Excess over 5000 30 In addition 6% of an employee’s gross wage is withheld for Social Security, 3% is withheld as constituency tax and 20GHS is withheld by the employer as welfare contribution. If an employee has more than 3 dependants then an amount of 5GHS for each dependant in excess of three towards NHIS. You are required to write a program that compute a workers gross pay, the deductions and his/her net pay. Your program should allow details of the staff to be accept /input into the system for the necessary computations. Try using comments in explaining the flow of the…
