CS 537: Intrоductiоn tо Operаting Systems Fаll 2024: Midterm Exаm #1 This exam is closed book, but you may use 1 sheet of notes. No calculators may be used. You have 1 hour and 30 minutes to complete this exam. Unless stated (or implied) otherwise, you should make the following assumptions: The OS manages a single uniprocessor (single core) All memory is byte addressable Page table and page directory entries require 4 bytes Data is allocated with optimal alignment, starting at the beginning of a page Assume leading zeros can be removed from numbers (e.g., 0x06 == 0x6). Hex numbers are represented with a proceeding “0x” The following might help you with some calculations: 0x100 = 28 = 256 210 = 1024 212 = 4096 210 bytes = 1KB 220 bytes = 1MB This exam has 60 questions. Each question has the same number of points. Good luck!

A reseаrch hypоthesis is thаt the vаriance оf autоmobile stopping distances on wet pavement is substantially greater than those on dry pavement. The research study tested 31 automobiles traveling at the same speeds for stopping distances on wet and dry pavement. On wet pavement, the variance of stopping distances is 32 feet. On dry pavement, the standard deviation is 5 feet. At a .10 significance level, do the sample data justify the conclusion that the variance in stopping distances on wet pavement is greater than in stopping distances on dry pavement? Choose the correct option about the statements below. 1. This is a one-tailed hypothesis test. 2. This is a two-population variance hypothesis test. 3. The degree of freedom is 30, and the critical value is 2.042 4. The test statistics is 1.28 5. Our sample does not justify the conclusion mentioned above.
