Question 17 (5 points) In the computer game World of Warcraft, some of the strikes are critical strikes, which do more damage. Assume that the probability of a critical strike is the same for every attack, and that attacks are independent. During a particular fight, a character has 271 critical strikes out of 504 attacks. What is the lower bound for the 99% confidence interval for the proportion of strikes that are critical strikes. Round to three decimal places (for...

Scientists want to estimate the mean weight of mice after they have been fed a special diet. From previous studies, it is known that the weight is normally distributed with standard deviation 5 grams. How many mice must be weighed so that a 95% confidence interval will have margin of error of 0.6 grams? Write only an integer as your answer. Six measurements were made of the mineral content (in percent) of spinach, with the following results. It is reasonable...
