Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
To estimate the "average" temperature in a city (in degrees F), you measure the temperature at a random sample of spots in the city. These values are shown in the table. 70.5 70.1 75.9 65.7 72.7 72.2 64.9 70.7 73.7 67.9 67.5 72.3 74.3 69.9 69.3 Build a 90% Cl for the mean temperature in the city. You may assume that temperatures follow a normal distribution. Keep at least 3 decimals in all intermediate steps, and round your answer to two decimals. Enter your CI like this: (min,max) Be sure to use the parentheses or you will be marked wrong. Submit Question MacBook Air F8 F9 F6 F7 F4 F5 F2 F3 2$ 3 4. 60 * 00 5

Each observation in a random sample of 98 bicycle accidents resulting in death was classified according to the day of the week on which the accident occurred. Data consistent with information are given in the following table. x² Day of Week Frequency = Sunday Monday Tuesday Wednesday Thursday Friday Saturday 13 12 12 14 13 18 Based on these data, is it reasonable to conclude that the proportion of accidents is not the same for all days of the week? Use a = 0.05. Calculate the test statistic. (Round your answer to two decimal places.) 16 Use technology to calculate the P-value. (Round your answer to four decimal places.)
