QUESTION 2 1 POINT Let's suppose a study is done by an accreditation group in two competing colleges to determine which one graduates students with more advanced classes. College 1 samples 8 graduates. Their average is 4 advanced classes with a standard deviation of 1.1 advanced classes. College 2 samples 14 graduates. Their average is 6 advanced classes with a standard deviation of 1.2 advanced class. The accreditation group believes that a student who graduates from college 1 has taken more advanced classes, on average. Both populations have a normal distribution. Perform a hypothesis test at a 5% significance level. Provide your answer below: is is not shown at the $5\%$ significance level that students from College 1 take more advanced classes than from College 2.

Question 17 1 pts In not viewing his condemnation to death as evil or wrong, Socrates is not angry with those who have accused, convicted and condemned him to death. Instead, he says he will consider himself justly treated by them if, as he says, "when my sons grow up, avenge yourselves by causing them the same kind of grief that I caused you," that is, reproach them as I reproach you Oif they do not care for the right things Oif they think they are somebody when they are nobody Reproach them as I reproach you if you think they care for money or anything else more than they care for virtue all of the answer choices are correct if they think they are worthy when they are not worthy of anything

Use calculus to prove that the relative minimum or maximum for any function f, as shown below, occurs at x equals negative StartFraction b Over 2 a EndFraction. f(x) = ax^2 + bx + c, where a ≠ 0 Question content area bottom Part 1 Where will the relative minimum or maximum for the function occur? a critical value an inflection point Part 2 Determine the derivative of the function f(x) = ax^2 + bx + c. f'(x) = Part 3 Determine the critical values of f(x) = ax^2 + bx + c. A critical value can occur where f'(x) = 0 and also where f'(x) does not exist. Since f'(x) is a polynomial, there are no x-values where f'(x) does not exist. Therefore, the only critical values will be where f'(x) = 0. Solve the equation f'(x) = 0 for x. x = Part 4 Prove that x = negative StartFraction b Over 2 a EndFraction is a maximum or a minimum. Determine f''(x). f''(x) = Part 5 Since f''(x) = 2a is a constant, if a < 0, 2a < 0 and f is concave down for all x and x = negative StartFraction b Over 2 a EndFraction is the maximum. If a > 0, 2a > 0 and f is concave up for all x and x = negative StartFraction b Over 2 a EndFraction is a minimum.

Write a program in C/C++ (or Python or Java), call it truthTableGen- erator, to generate the truth table of 3-variable Boolean functions, with the following requirements: • Your program takes as input a 3-variable Boolean function in the form of a sum-of-products. For example, the input can look like "AB" + "??'?" + "A'B'C". The double quotations are needed so that the ' is taken as a regular character, negating the preceding variable, and not considered a special character. • The evaluation of each term, e,g., AB'C, is done in a separate function, called, evalTerm(int A, int B, int C, char *term) that return the Boolean value (0 or 1) of the corresponding term. • Your program should print the Boolean function followed by its truth table. • You can test the uploaded Linux-executable to understand all the require- ments. Test runs: • $ truthTableGenerator // call without arguments $ Truth table generator for 3-variable Boolean functions $ Usage: enter a Boolean function as a sum of products $ E.g.: ./a.out "AB" + "BC" + "A'BC" • $ truthTable Generator "AB" + "BC" + "ABC" + "A'B'C'" F is the sum of 4 product terms F = AB' + BC' + ABC + A'B'C'
