A manufacturer knows that the number of items produced per hour by machine A and by machine B are normally distributed with a standard deviation of 4.4 items for machine A and a standard deviation of 6.7 items for machine B. The mean hourly amount produced by machine A for a random sample of 54 hours was 226 units; the mean hourly amount produced by machine B for a random sample of 45 hours was 215 units. Find a 99% confidence interval for the difference in mean parts produced per hour by these two machines. t The confidence interval is

Write the answers as a fraction in reduced form.Do you know what regifting is? It is loosely defined as "giving someone a gift that was originally given to you without telling the recipient the origin of the gift." Now that you know, how often do you engage in regifting? In a survey of 5555 persons, the answers to that question were as follows. Response to the question: How often do you engage in regifting?Very often → 146 votesEvery now and then → 819 votesNot very often → 1756 votesNever → 2808 votesI'm not sure → 26 votesCurrent number of voters: 5555 If one of the persons is selected at random, what is the empirical probability of the following? (a) The person very often engages in regifting. (b) The person never engages in regifting.(c) If you get a gift and you assume that the results of the survey apply to that gift, what is the probability that you are getting a regift? Assume that the people who give regifts are the ones that did not answer "Never."
