A sample of 900 computer chips revealed that 68% of the chips fell in the first 1000 hours of their use. The companies promotional literature states that 67% of the chips fail in the first 1000 hours of their use.

The Computer Anxiety Rating Scale (CARS) measures an individual’s level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at a large university administered CARS to 80 business students. One of the objectives of the study was to determine whether there is a difference between the level of computer anxiety experienced by female students and male students. Of the 80 student survey takers, 40 were male, 40 were female. The results are in the table below for statistical analysis of variability between the two samples. All of these analyses are run with a 95% level of confidence. Males Females Sample Mean 40.26 36.85 Sample Standard Deviation 13.35 9.42 Perform the test chosen in part (d) of the previous problem and supply this information: a. What is the value of the test statistic? b. Find the probability of getting these results if there is no difference in anxiety ratings between the…
A magazine provided results from a poll of 2000 adults who were asked to identify their favorite pie. Among the 2000 respondents, 11% chose chocolate pie, and the margin of error was given as ±3 percentage points. Describe what is meant by the statement that "the margin of error was given as ±3 percentage points." Choose the correct answer below. A. The statement indicates that the study is 100% - 3% = 97% confident that the true population percentage of people that prefer chocolate pie is 11%. B. The statement indicates that the interval 11% ± 3% is likely to contain the true population percentage of people that prefer chocolate pie. C. The statement indicates that the study is only 3% confident that the true population percentage of people that prefer chocolate pie is exactly 11%. D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 11% ± 3%.
