Typical Vickers indentation on a 4 vol% carbon nanotube (CNT) reinforced ZrB2 ceramic composite shows cracks emanating from the indentation corners (see figure). The indentation was obtained using load of 1000 g and holding time of 15 s (Vickers Hardness tester). Fracture toughness and Hardness of material are given by expressions: 1/2 0.016(5) H/2 1.854P where E is Young's Modulus of the composite (GPa); H is Vickers Hardness (GPa); P is applied load (N); c is diagonal crack length emanating...

Refer to the following three sets of facts as situation A. Suppose that the number of passengers flown on all of United flights is 223, 175, 322, 196, 257, 274, 311, 212, 213, 189, 194, 199, 204, etc. We take a sample of 25 of these flights and the passengers flown were 200, 175, 186, 199, 205, 204, 202, 294, 264, etc. (the remaining figures are not shown). We take the average of that sample and 36 more samples and...

Worksheet: Chi Square and Correlation Suppose we have three categories A, B, and C. Assume that the historical distribution of observations among these four categories is 20%, 40%, and 40% respectively. A sample of size 250 is taken, and we find 75 observations in category A, 125 in category B, and 50 in category C 1. a. State the null hypothesis for the Chi-square goodness-of-fit test. b. What are the expected frequencies for each category? c. Calculate the χ 2...

[15 marks] Suppose that students enrolled in one course are required to take four tests, and each student’s final grade for this course is the average of his/her grades of these four tests. This question asks you to write a program that can be used to compute the lowest final grade, highest final grade and the average final grade. General Requirements: Use a5q1.c as the name of your C source code file. We will use the following command on bluenose...

QUESTION 1 There are dozens of personality tests available on the World Wide Web. One test, scored on a scale of 0 to 200, is designed to give an indication of how "personable" the test taker is, with higher scores indicating more "personability." Suppose that scores on this test have a mean of 96 and a standard deviation of 24. Complete the following statements about the distribution of scores on this personality...
