10.11. Steel rods with 10 mm diameters are used in the construction of bridges. The steel rods are used only if their yield stress exceeds 490. The state government is reviewing the product of one manufacturer to possibly use in the construction. The product will be tested before issuing a contract. What null and alternative hypotheses should the state government test to determine whether the steel rods meet the requirement? 10.12 Refer to the situation in Exercise 10.11. a. Describe type I and type II hypotheses that the state government could possibly make. b. Describe consequences of making such errors.
The manufacturer of a certain engine treatment claims that if you add their product to your engine, it will be protected from excessive wear. An infomercial claims that a woman drove 3 hours without oil, thanks to the engine treatment. A magazine tested engines in which they added the treatment to the motor oil, ran the engines, drained the oil, and then determined the time until the engines seized. Complete parts (a) and (b) below. (a) Determine the null and alternative hypotheses that the magazine will test. UpperH0: ▼ muμ sigmaσ pp ▼ not equals≠ less than< greater than> equals= 3 Upper H1: ▼ muμ sigmaσ pp ▼ not equals≠ equals= less than< greater than> 3 (b) Both engines took exactly 17 minutes to seize. What conclusion might the magazine make based on this evidence? A. The infomercial's claim is true. The Informericial not true
A company specializes in producing bunkers located in places with extremely cold climates under 0°C. A prototype for a new bunker design using different structure design and materials was tested to have the following average interior temperatures: 23.01, 22.22, 22.04, 22.62, and 22.59. Test that the average interior temperature is equal to 22.5 °C using α = 0.05. a.What are the hypothesis statements?

Using traditional methods it takes 8.5 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. Set up the hypotheses to test the claim at the 0.01 level that the new technique lengthens the training time. State the null and alternative hypotheses for the above scenario.
For the given scenario determine the type of error that was made, if any .(hint begin by determining the null and alternative hypothesis. )A cell phone company claim only $50 as the main amount to its customers spend on cell phone service per month. One skeptical customer claims that the main amount its customers being on a cell phone service per month is different from $50. The skeptical consumer conduct a part of this test and fails to reject the null hypothesis. Assume that in reality the main amount its customers stand on cell phone service per month is $45. Was an error made? If so what type.
Located below is a list of examples of hypotheses. You must critique each hypothesis and assess if it is testable and written properly. Otherwise, revise the statement and make it a good one. 1. If the salary of employees will increase, then employees will be happier.2. The students got higher scores in the exam because the class size is small.3. A farmer observed that during seasons of drought and soil becomes more saline, his tomato plants were more susceptible to fungal infection. The combination of salinity and drought and the infestation of fungi led to significant reductions in fruit yield and size. The farmer proposes a general hypothesis, “Salinity and drought affect the severity of fungal infection in tomato plants.”
