Problem#6 19. Age of Death-Row Inmates In 2002, the mean age of an in- mate on death row was 40.7 years, according to data obtained from the U.S. Department of Justice. A sociologist wondered whether the mean age of a death-row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is 38.9, with a standard deviation of 9.6. Construct a 95% confidence interval about the mean age. What does the interval imply? Answers: Fail to Reject Ho: t(critical) = -2.0395, t-value = -1.06. Cl = 42.36 - 35.44

Use R to solve the following tasks. TASK 1. Estimate the following probabilities by simulation (we don't want to see any analytical approaches!) In your report explain your code and show your answers. a. You have all the black cards from a normal deck, I have all the red cards. We each choose one card from our half decks - the highest card wins. But I have managed to sneak out and throw away your 9 Of Clubs! Simulate 1000 games - how many did I win? (Ace is low.) b. There are 87 people on a bus - what is the likelihood that two of them share a birthday? c. How many people would you need to gather together before there is a 90% chance that one of them was born on the 1st Jan?

In bivariate regression, the regression coefficient will be equal to rXY when:
The price of a certain combo meal at different franchises of a national fast food company varies from $5.00 to $17.38 and has a known standard deviation of $2.13. A sample of 29 students in an online course that includes students across the country stated that their average price is $5.75. The students have also stated that they are generally unwilling to pay more than $6.50 for this meal. Formulate and conduct a hypothesis test to determine if you can conclude that the population mean is less than $6.50. Use a level of significance of 0.05. Is there sufficient evidence at the 0.05 level of significance that the population mean is less than $6.50? Determine the null hypothesis, Ho, and the alternative hypothesis, H,. Họ: H 6.50 < 6.50 (Type integers or decimals. Do not round.) Compute the test statistic. - 1.90 (Round to two decimal places as needed.) Find the p-value for the test. (Round to three decimal places as needed.)
Martin created a website where users could randomly generate a "strong password." He claims that 22% of generated passwords contain at least one capital letter, number, and symbol. If the claim is correct, and a user randomly generates 5 passwords on the website, what is the probability that exactly 4 of the passwords contain at least one capital letter, number, and symbol?
