I'm having some struggle with this problem and I need some help with it, please? 33. Mean Age of Female Statistics Students Data Set 1 “Body Data" in Appendix Bincludes ages of 147 randomly selected adult females, and those ages have a standard deviationof 17.7 years. Assume that ages of female statistics students have less variation than ages offemales in the general population, so let o = 17.7 years for the sample size calculation. Howmany female statistics student ages must be obtained in order to estimate the mean age of allfemale statistics students? Assume that we want 95% confidence that the sample mean is withinyear of the population mean. Does it seem reasonable to assume that ages of femaleone-halfstatistics students have less variation than ages of females in the general population? Sample Size. In Exercises 29–36, find the sample size required to estimate the popula-tion mean.

Use duality to answer the following application. The Enormous State University's Business School is buying computers. The school has two models to choose from, the Pomegranate and the iZac. Each Pomegranate comes with 400 GB of memory and 80 TB of disk space, while each iZac has 300 GB of memory and 100 TB of disk space. For reasons related to its accreditation, the school would like to be able to say that it has a total of at least 61,500 GB of memory and at least 15,700 TB of disk space. If both the Pomegranate and the iZac cost $2,000 each, how many of each should the school buy to keep the cost as low as possible? (pomengranates, iZacs) = What are the shadow costs of memory and disk space? memory $4 per GB disk space per TB
Remark:You will have 5 questions regarding the same problem but in each question the numbers will be different An advertising company offer three types of mediums: television, newspaper and radio. The cost for each medium with its audience coverage is given below. Television Newspaper Radio Cost per advertisement ($) 1900 1000 100 Audience per advertisement 93,000 38,000 15,000 The company is capable of using a number of newspaper advertisement slots up to 13. Moreover, in order to balance the advertising among the three types of media, the total number of advertisements on radio should not occur more than 45% of total number of advertisement and at least 12% of the total number of advertisements should occur on television. The weekly advertising budget is $23800. How many advertisements should be run in each of the three types of media to maximize the total audience? If we assume the number of ads on each type of meduim as follows : T, N, R respectively Given the following objective…
You are opening a plant that will manufacture widgets (w) and gizmos (g). The widget machines cost $10,000 each. They each require 4 operators and 500 square feet o space. The gizmo machines each cost $6,000 ard require 6 operators and 500 square feet of space. Your new plant has 40,000 square feet of space available for the machines. HR estimates that you will be able to hire 460 operators to run the machines. Your budget for buying machines is $660,000. a) List all 5 constraints. b) List the coordinates of the corners of the graph in (g,w) form. (We cannot buy a fraction of a production machine. If the corners are not whole numbers, give the closest whole number coordinates along each constraint line.) c) Given the following estimated profits per hour per machine in each scenario, how many of each type of machine should you buy? What will be your profit per hour at tha Profit per Maximum Profit per Widget Number of Gismos Number of Widets Gizmo Profit $99 $98 $78 $120 $265 $103 ts…

A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…

You are thinking of making your home more energy efficient by replacing some of the light bulbs with compact fluorescent bulbs and insulating part or all of your exterior walls. Each compact fluorescent light bulb costs $4 and saves you an average of $2 per year in energy costs, and each square foot of wall insulation costs $1 and saves you an average of $0.20 per year in energy costs.† Your home has 60 light fittings and 1,200 square feet of uninsulated exterior wall. You can spend no more than $1,300 and would like to save as much per year in energy costs as possible. How many compact fluorescent light bulbs and how many square feet of insulation should you purchase? Please don't give handwritten answer..thanku
