An engineer wishes to design a test to find the mean resistance of a wire. He wants to determine a sample size so that if the mean is different than 0.8 ohms (say, in reality the mean is more than 0.15 ohms different from 0.8 in either direction), the test will detect this with high probability, like 90%. The standard deviation is known to be 0.9 and the significance level of the test 0.08. What is the required sample size? 110.25

K Conduct a test at the α = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether p₁> P2. The sample data are x₁ = 116, n₁ = 244, x2 = 132, and n₂ = 313. (a) Choose the correct null and alternative hypotheses below. OA. Ho P1 P2 versus H₁: P1 P2 OB. Ho P₁ P2 versus H₁: P₁ P2 OD. Ho p₁ =0 versus H₁:.p₁ #0 (b) Determine the test statistic.

A desired (standard) temperature is set by adjusting a lever or wheel on the thermostat. A mechanism such as a bimetallic strip or bellows converts the actual temperature surrounding the thermostat into physical movement. When the variance between desired and actual temperature exceeds some design maximum, sensor movement creates an electrical contact that communicates a signal to the correcting entity, in this case the control of a furnace or air conditioner, and the variance is automatically corrected. The output of a system can be measured and the variance between measured and desired output is used to adjust the system.
