Rita has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via 60 Freeway. In order to determine which way she should travel on a daily basis, Rita has recorded the travel times for samples of twelve trips via the 10 Freeway and twelve trips via the 60 Freeway. The following table gives the travel times (in minutes) for the twenty-four trips. Travel times in minutes 10 Freeway 66, 70, 73, 71, 72, 71, 65, 74, 69, 71, 75, 71 60 Freeway 77, 72, 71, 68, 74, 80, 70, 78, 76, 71, 68, 67 Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.01 level of significance, that the mean travel time via the 10 freeway, μ1, is different from μ2, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and…

Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a certain country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively. Blood Types A+ A− B+ B− AB+ AB− O+ O− Percent 35.7 6.3 9.5 2.5 3.4 0.8 37.2 4.6 (a) What is the probability that a person selected randomly from the population has a blood type that is type O or Rh+?(b) What is the probability that a person selected randomly from the population has a blood type that contains the A antigen?(c) What is the probability that a person selected randomly from the population has a blood type that is type AB or Rh−?
