A problem with polling is whether or not people are willing to answer honestly. If aquestion might be viewed as shameful or embarrassing (about politics, sexual activity,etc.), they may be reluctant to answer honestly.A potential solution to this is the following: let's suppose that 'YES’ is the embarrassingor socially shameful answer. Give the people you are polling the following instructions:flip a coin privately, and if it comes up heads, you must answer honestly. However, if itcomes up tails, you must answer 'YES’ regardless of what the truth is. This gives peopleлplausible deniability about why they answered yes, if pressed. Again, let p,be thefraction of people who said 'YES'. Let p be the probability that a randomly selectedperson says YES’. Let q be the probability that a person’s true answer is 'YES’. Noteлagain, we have that the expected value of p,, is p, but we are actually interested inNmeasuring q. What is the relationship between q and p?

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…
