Aconsumer products company is formulating a new shampoo and is interested in foam height (in millimeters). foam height is approximately normally distributed and has a standard deviation of 20 millimeters. the company wishes to test latex: h_{0} =\mu =175h0==175 millimeters versus latex: h_{1} =\mu > 175h1=> 175 millimeters, using the results of n samples. find the boundary of the critical region if the type i error probability is latex: \alpha =0.=0.05 and n=4

In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
