Unit 5 Assignment 1: Homework Short Answer 1-7 p.158 1) Explain what is meant by the term “conditionally executed”. Conditionally executed is called a single alternative decision structure because it provides only one alternative path of execution. The action is conditionally executed because it is performed only when a certain condition is true. 2) You need to test a condition and then execute one set of statements if the condition is true. If the condition is false, you need to execute a different set of statements.
Assignment #2 1) Improve the result from problem 4 of the previous assignment by showing that for every e> 0, no matter how small, given n real numbers x1,...,xn where each xi is a real number in the interval [0, 1], there exists an algorithm that runs in linear time and that will output a permutation of the numbers, say y1, ...., yn, such that ∑ ni=2 |yi - yi-1| < 1 + e. (Hint: use buckets of size smaller than 1/n; you might also need the solution to problem 3 from the first assignment!) 2) To evaluate FFT(a0,a1,a2,a3,a4,a5,a6,a7) we apply recursively FFT and obtain FFT( a0,a2,a4,a6) and FFT(a1,a3,a5,a7). Proceeding further with recursion, we obtain FFT(a0,a4) and FFT(a2,a6) as well as FFT(a1,a5) and FFT(a3,a7). Thus, from bottom up, FFT(a0,a1,a2,a3,a4,a5,a6,a7)
(a) Find a 99% confidence interval for the true mean heart rate of all people with this untreated condition. Show your calculations. (b) Interpret this confidence interval and write a sentence that explains it. 23. Determine the minimum required sample size if you want to be 80% confident that the sample mean is within 2 units of the population mean given sigma = 9.4.
