Under ordinary circumstances: For all babies born in the entire global population, the proportion of male births tends to be consistently a bit higher, than the proportion of female births (Source: WHO  World Health Organization).
In fact: For a randomly sampled individual birth from the global population, the probability that the baby's sex will be male is approximately 51.22%.
Imagine that we will randomly record the sex outcome at birth for 25 future individual babies from the global population.
We will let random variable X stand for the total number of male births in our sample.
In this scenario, what is the numerical value of E(X)?
Round to one digit past the decimal point, and state just the number part of your answer (no units).
In this same scenario:
What is the numerical value of SD(X)?
Round to one digit past the decimal point, and state just the number part of your answer (no units).
In this same scenario:
What is the approximate value of P(X≤11) ?
Write your answer as a percentage value, and round to three digits after the decimal point. Include a percent symbol after your answer (no spaces).
In this same scenario:
What is the approximate value of P(X>11) ?
Write your answer as a percentage value, and round to three digits after the decimal point. Include a percent symbol after your answer (no spaces).

Instructions: Using the following data, complete the requirements given below. When you are given amounts to assume as the answers to previous requirements, be careful to use such assumed amounts rather than your answers (in order to minimize carrythrough errors).
The Finishing Department of Curtis Corporation reports the following for January 2011:
Production: All materials are added at the beginning of the process. Beginning work in process 20,000 units, 60% complete. Units started into production 240,000 units. Ending work in process 10,000 units, 30% complete.
Manufacturing Costs: Beginning work in process, $40,000, comprised of $15,000 of materials and $25,000 of conversion costs. Materials added $160,000; labor and overhead added $465,000.
(a) Required: Compute equivalent units of production for (1) materials and (2) conversion costs.
(b) Assume your answers to (a) above were 250,000 units for materials and 245,000 for conversion costs. Required: Compute the unit costs for the month.
(c) Assume your answers to (b) above were $.90 for materials and $2.10 for conversion costs. Required: Determine the costs to be assigned to the 240,000 units transferred out.
(d) Assume the same unit costs as given in (c) above. Required: Determine the costs assigned to the 10,000 units in ending work in process.

Using an excel spreadsheet to present your work, calculate the projected revenue collected from federal income taxes, state income taxes, and the local payroll tax for FY 2014 and prepare a revenue estimate for the City of Newark’s Public School System for FY 2015 based on the following information. Assume that no other deductions came from the employee’s salary other than what is listed here. Hint: New employees are not eligible for raises, which are based on performance from the previous fiscal year. (See Table below for format. You are to prepare two spreadsheets (projected revenue and revenue estimate))...Show formulas for calcualtions
FY 2014 Facts:
1 The school system currently has 34 fulltime employees. There is one superintendent, two principals, three janitors, ten kitchen staff, and eighteen teachers (including coaches).
The superintendent has a salary of $95,000
Each principal has a salary of $70,000
Four of the teachers (Teacher A) had salaries of $55,000; six teachers (Teacher B) had salaries of $45,000 and six teachers (Teacher C) had salaries of $40,000
The remaining two teachers (A Level) are also coaches. The football coach receives and additional $5,000 in salary and the basketball coach receives and additional $7,000 in salary each year.
Mrs. Jones manages the kitchen. Her FY 2014 salary was $45,000
The remaining kitchen staff made $28,000 each in FY 2014
The three janitors made $25,000 each in FY 2014
Use these federal income tax rates: $0  $8,700.99 = 10%; $8,701  $35350.99 = 15%; $35,351  $85,650.99 = 25%; $85,651  $178,650.99 = 28%; $178,651  $388,350.99 = 33%; >$388,351 = 35%. The tax rates were the same in FY 2014 and FY 2015.
The state income tax rate is 4% for the first $3,000 of employee salary and 5.5% on everything above that amount. The rate is the same in both years.
The local payroll tax is 1.75% in FY 2014 and 1.85% in FY 2015.
FY 2015 Facts:
In FY 2015, the school system hired two more teachers at the Teacher D level. They will begin work in FY 2015 at a salary of $35,000.
In FY 2015, each school employee received a 5% raise except the principals and superintendents. They received a 2% raise. Note, new employees, do not receive a raise.
