Measuring the actual dimensions of a manufactured part is a classical problem in many differentdisciplines, particularly for quality engineers. A quality engineer is measuring the thickness ofnickel plates for use in a nickel-hydrogen battery. By the way the plate is made, she canconsistently identify specific locations on each plate. That is, location A is in the same spot oneach plate, and location B is in the same spot on each plate. She believes that measuringthickness at location A results in a consistently thicker measure than at location B. Shemeasured thickness, in mm, at locations A and B on the same 10 plates. Conduct an appropriatehypothesis test with 95% confidence using the critical value approach.Location ALocation B31.10 31.1029.75 29.7530.9030.15 30.8030.8032.2030.2030.4030.4029.65 29.85 29.85 30.6530.35 29.75 29.15 30.50

5. Josh is planning to paint the walls and ceilings in several rooms of his home. The walls have a combined area of 1840 ft². The ceilings have a combined area of 920 ft². The walls will require 2 coats of paint, and the ceilings will take a single coat of paint. Each gallon of paint covers about 240 ft². How many gallons of paint are needed for the walls? How many gallons of paint are needed for the ceilings? Round up to the nearest whole gallon if necessary.

11. How much would it cost for the gold to cover the exterior of the City Hall's dome in gold leaf, given the following information? • City Hall's dome is hemispherical in shape (half a sphere). • The diameter of the dome is 20 meters. • One ounce of gold costs $400 and can be beaten into a thin 15 square meter sheet of gold leaf. • Gold must be purchased in whole ounces. • The volume of a sphere is given by 4/3 x T x 3. • The surface area of a sphere is given by 4 x T x r2. • You may approximate t by 3.14. Type only the nearest whole number. Do not provide units.
Joe owns a coffee shop, and he has two measures of coffee drink quality that he has been using over the years to assess the quality of coffee drinks: 1) the grind level (in units 1, 2, 3, 4, 5), and 2) the temperature of the water pouring over the ground beans (in units 10, 20, 30, 40). Ultimately, a measure of quality is how well things sell! So, he collects sales (in 100 dollars) for a month, and comes-up with the following data. The questions are a) does grind level have predictive validity for sales? Yes/No, but also provide appropriate graphs and analysis. b) Does water temperature have predictive validity for sales? Yes/No, but also provide appropriate graphs and analysis. c) If Joe had to choose only one of the measures, which one should it be?

A box is formed by cutting squares from the four corners of a 7"-wide by 9"-long sheet of paper and folding up the sides. Let x represent the length of the side of the square cutout (in inches), let w represent the width of the base of the box (in inches), let l represent the length of the base of the box (in inches), let h represent the height of the box (in inches), and let V represent the volume of the box (in cubic inches). Complete the table of values below. If an entry cannot be completed, enter "DNE". h V 7 9 0.5 DNE 0.5 5 3.5 3.5
A router is used to cut locating notches on a printed circuit board. The vibration level at the surface of the board as it is cut is considered to be a major source of dimensional variation in the notches. Two factors are thought to influence vibration: bit size (A) and cutting speed (B). Two bit sizes (1/16 and 1/8 inch) and two speeds (40 and 90 rpm) are selected, and four boards are cut at each set of conditions shown below. The response variable is vibration measured as a resultant vector of three accelerometers (x, y, and z) on each test circuit board. (a) Analyze this experiment assuming that each one of the four replicates represent a block. (b)
The density of pure iron is 7.874 g/cm.Apiece of steel made of pure iron and other types of iron is in the shape of a rectangular pyramid. The rectangular pyramid has a base edge length of 4 cm, a base edge width of 9 cm, a height of 5 cm, and a mass of 425 g. What is the difference between the density of pure iron and the density of the steel rectangular pyramid? Round your answer to the nearest thousandth. Type your answer.
