A company claims that the mean monthly residential electricity consumption in a certain region is more than 890 kiloWatt-hours (kWh). You want to test this claim. You find that a random sample of 68 residential customers has a mean monthlyconsumption of 930 kWh. Assume the population standard deviation is 123 kWh. At a= 0.10, can you support the claim? Complete parts (a) through (e).(a) Identify Ho and H. Choose the correct answer below.O A. Ho: us 930H:u> 930 (claim)B. Ho: HS 890H:u> 890 (claim)OC. Ho: u>930 (claim)H: us 930OD. Ho: = 930H:u#930 (claim)O E. Ho: = 890 (claim)H: u# 890OF. Ho: p> 890 (claim)H:us 890(b) Find the critical value(s) and identify the rejection region(s). Select the correct choice below and fill in the answer box within your choice. Use technology.(Round to two decimal places as needed.)O A. The critical value isO B. The critical values are t

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.7 parts/million (ppm). A researcher believes that the current ozone level is not at the normal level. The mean of 13 samples is 4.9 ppm with a standard deviation of 1.0. Does the data support the claim at the 0.1 level? Assume the population distribution is approximately normal. Step 3 of 3: Make the decision to reject or fail to reject the null hypothesis.
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.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.5 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 66 samples is 7.7 ppm with a standard deviation of 1.0 Does the data support the claim at the 0.025 level? Assume the population distribution is approximately normal. Step 2 of 5 : Find the value of the test statistic. Round your answer to three decimal places. Specify if the test is one-tailed or two-tailed. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
