6. A small company can employ 3 workers. Each worker independently stays on the job for an exponentially distributed time with a mean of one year and then quits. When a worker quits, it takes the company an exponentially distributed time with a mean of 1/10 of a year to hire a replacement for that worker (independently of how long it takes to replace other workers). If the company takes in $1000 per day in revenue when it has 3 workers, $800 per day when it has 2 workers, and $500 per day when it has 0 or 1 workers, what is the company's long-run average daily revenue?
Question: A researcher conducts a study of familiarity with certain unusual words and the time it takes a participant to press a button indicating whether the word is singular or plural. All participants rate their familiarity with these on a scale of 1-7 (7 being highly familiar). All participants are timed as well and their reaction time is recorded in seconds. The raw scores from the three participants are listed below . Participant Familiarity rating (X) Reaction time (seconds) (Y) 1 6 1 2 2 3 3 3 4 a) Calculate the correlation coefficient. b) Does this mean that familiarity causes fast reaction time? Why or why not? c) Predict the raw reaction time for a familiarity rating of 4. d) What is the proportion of variance…

Understanding hypothesis tests in general: One use of a Chi-square test is to determine whether factors are independent from each other or dependent on each other. For example, consider the following: A marketer, who works for a brewery, has to promote a new beer. She samples 150 people and wants to determine whether there is an association between gender and beer preference. If there is an association, then it means that a persons beer preference can be predicted by knowing the persons gender. The results are: Beer preference Gender Light ale Lager Best bitter Total Male 20 40 20 80 Female 30 30 10 70 Total 50 70 30 150 The null hypothesis always says that the factors are independent, i.e. H0: Beer preference and Gender are independent The alternative hypothesis always says the opposite, i.e. H1: Beer preference and Gender are dependent The hypothesis test was performed at the 2.5% level of significance and the p-value was found to be 0.0149.
