Problem 5 (Marybeth is also interested in the experiment from Problem 2 (associated with the enhancements for CaptainAmerica's shield), so she decides to start a detailed literature review on the subject. Among others, she founda paper where they used a 2"(4-1) fractional factorial design in the factors: (A) shield material, (B) throwingmechanism, (C) edge modification, and (D) handle adjustment. The experimental design used in the paper isshown in the table below.a.RunABсD1(1)-1-1-112a1-1-113bd-11-114abd11-115cd-1-11-16acd1-11-17bc-111-1abc111-1paper?s) What was the generator used in the 2"(4-1) fractional factorial design described in theb.Based on the resolution of this design, what do you think about the generator used in thepaper? Do you think it was a good choice, or would you have selected a different one? Explain youranswer in detail.

1. A study was conducted to investigate the effects of three factors on the fragmentation of an explosive device. The factors of interest are pipe diameter, a restraint material and the air gap between the device and the restraint material. Two repeat tests were conducted on each combination of the factor levels. The data are shown below. (a) (b) (c) Air gap (C) Factors A (in.) B C (in.) Material (B) 0.50 in. 0.75 in.

Question 2 The Mystic Coffee Shop blends coffee on the premises for its customers. It sells three basic blends in bulk on one-kilogram bags: Special, Mountain Dark, and Mill Regular. It uses four different types of coffee to produce the blends: Brazilian, mocha, Colomnian, and mild. The shop uses the following blend recipe requreiements: Blend Mix Requirements Special Dark Regular At least 40% Columbian, at least 30% mocha At least 60% Brazilian, no more than 10% mild No more than 60% mild, at least 30% Brazilian Selling price / kg $6.50 5.25 3.75 The cost of Brazilian coffee is $2.00 per kg, the cost of mocha is $2.75 per kg, the cost of Columbian is $2.90 per kg, and the cost of mild is $1.70 per kg. The shop has 110 kilograms of Brazilian coffee, 70 kilograms of mocha, 80 kilograms of Columbian, and 150 kilograms of mild coffee available per week. The shop wants to know the amount of each blend it should prepare each week to maximize profit. Formulate and solve a linear programming…
Josh wants to convince his mother to stop buying single-ply toilet paper. Josh believes that even though Fluffy, a two-ply toilet paper costs more, it will last longer because it is more absorbent. To help substantiate his claim, Josh performed a study. He purchased a random sample of 18 rolls of Fluffy. For each roll, he determined how many squares are needed to completely absorb one-quarter cup of water. Here is a dotplot of the data. The mean of the sample is 24.444 squares with a standard deviation of 2.45 squares. Single-ply toilet paper requires 26 squares to absorb one-quarter cup of water. Josh would like to carry out a test to determine if there is convincing evidence that the mean number of squares of Fluffy that are needed to absorb one-quarter cup of water is fewer than 26 squares. What is the appropriate test statistic and P-value of this test? (A) z = -2.69z=−2.69, PP-value = 0.0036=0.0036 (B) t = -2.69t=−2.69, PP-value = 0.0078=0.0078 (C) t = -2.69t=−2.69, PP-value =…
Psychologists at Disney World measured factors that affect the scariness of the soundtrack for their Haunted House ride. In particular, they were interested in the loudness of the screams (soft versus loud) and the length of the screams (short versus long). They used a 2 × 2 factorial design to test how these factors combined. They collected data from 10 different riders in each of the four conditions. Each rider rated the scariness of the ride on a nine-point scale. short screams long screams soft screams T=38, n = 10, SS = 13.6 T=64, n = 10, SS = 22.4 loud screams T=52, n=10, SS = 29.6 T=50, n=10, SS = 16.0 For these data: G = 204, N = 40, X2 = 1156. 1. Sketch a dataplot of the mean rating in each condition. 2. Calculate SS total, the total sum of squares 3. Calculate SSwithin, the within-treatments sum of squares. 4. Calculate SSbetween, the between-treatments sum of squares. 5. Calculate SSA the sum of squares for Factor A (length of scream). 6. Calculate SSB, the sum of squares…
The manufacturing company in problem 3.60 also produces electric insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing how many pounds must be applied to an insulator before it breaks. Data are collected from a sample of 30 insulators. The file contains the strengths, as follows: 1,870 1,728 1,656 1,610 1,634 1,784 1,522 1,696 1,592 1,662 1,866 1,764 1,734 1,662 1,734 1,774 1,550 1,756 1,762 1,866 1,820 1,744 1,788 1,688 1,810 1,752 1,680 1,810 1,652 1,736 a. Compute the mean, median, range, and standard deviation for the force needed to break the insulators. Show your working. b. Interpret the measures of central tendency and variability in (a).

Problem 11-18 (modified). NASA scientists obtained the following data from airborne radiometer scans using the ESTAR method of aperature synthesis. Soil Moisture Percentages: 19,16,15,16.5,15,14 Source: D. M. LeVine, A. J. Griffis, C. T. Swift, and T. J. Jackson, "ESTAR: A Synthetic Aperature Microwave Radiometer for Remote Sensing Applications," Proceedings of the IEEE, December 1994, p. 1795. These data represent sample measurements taken over the 220-240 degree K brightness temperature range. The theoretical model states that the mean volumetric soil moisture percentage should be 13.5%. Use the confidence interval approach to conclude whether the sample data support or refute the null hypothesis that the mean ESTAR measurements equal the theoretical level, using a .05 level of significance. Lower 95% confidence limit= Upper 95% confidence limit= . What is your conclusion? O Reject Ho Accept Ho
