- 1. A recent survey showed that from a sample of 500 packages delivered by a Postal Service, 480were delivered on time. a) Construct a 95% confidence interval for the proportion of all packages that are deliveredon time by the Postal Service.Two men, A and B, who usually commute to work together decide to conduct an experiment to see whether one route is faster than the other. The men feel that their driving habits are approximately the same, so each morning for two weeks one driver is assigned to route I and the other to route II. The times, recorded to the nearest minute, are shown in the following table. Using this data, find the 95%confidence interval for the true mean difference between the average travel time for route I and the average travel time for route II. Let d=(route I travel time)−(route II travel time)d=(route I travel time)−(route II travel time). Assume that the populations of travel times are normally distributed for both routes.

- A supplier of eggs to grocers nationwide studied the mean egg length of eggs produced at their farms After selecting a random sample of eggs, they obtained a 95% confidence interval of (45 mm 60 mm) In the context of the problem, which of the following interpretations is correctif any? Choose the correct answer below A. We're 95% confident that the mean length of eggs from this supplier is between 45 mm and 60 mm B. We're 95% confident that an egg from this supplier will be between 45 mm and 60 mm in length For this particular population95% of all eggs from this supplier are between 45 mm and 60 mmin length. . We're 95% confident that the mean length of eggs in the sample is between 45 mm and 60 mm E. None of the above is a correct interpretationThe world’s smallest mammal is the bumblebee bat, also known as the Kitti’s hog-nosed bat(or Craseonycteris thonglongyai as it is a ectionately called). Such bats are roughly the sizeof a large bumblebee. Listed below are the weights (in grams) from a sample of these bats.Construct and interpret a 95% confidence interval of the “standard deviation” of weights of allsuch bats.bats=c(1.7,1.6,1.5,2,2.3,1.6,1.6,1.8,1.5,1.7,2.2,1.4,1.6,1.6,1.6)Out of a 54 person sample from our fall Math-150 classes, 12.4% of the students are left-handed. Using a TI 84 graphing calculator: Construct an 80% confidence interval for the population proportion, p. Round to tenths of a percentand write a sentence answer.The U.S. has 13.1% of it’s population that are left-handed. Did this fall in your confidence interval from part a?
