PLEASE SHOW COMPLETE SOLUTION WITHIN 30 MINUTES Two types of plastic are suitable for an electronics component manufacturer to use. The breakingstrength of this plastic is important. It is known that σ₁ = ₂ = 1.0 psi. From a random samplesize n₁ = 10 and n₂ = 12, you obtain ₁ = 162.5 and ₂ = 155.0. The company will not adoptplastic 1 unless its mean breaking strength exceeds that of plastic 2 by at least 10 psi.Based on the sample information, should the company use plastic 1? Use a = 0.05.a. Reject the Null Hypothesis. Zo = -5.84b. None among the choicesO c. Fail to reject the Null Hypothesis. P-value > 0.05d. Fail to reject the Null Hypothesis. Zo < 1.65

A large manufacturing company investigated the service it received from its suppliers and discovered that, in the past, 38% of all material shipments were received late. However, the company recently installed a just-in-time system in which suppliers are linked more closely to the manufacturing process. A random sample of 150 deliveries since the just-in-time system was installed reveals that 33 deliveries were late. If we want to test whether the proportion of late deliveries was reduced signicantly at = 0:10 the null and alternative hypotheses are a. Null hypothesis (H0) b. Alternative hypothesis (HA)

Researchers interested in lead exposure due to car exhaust sampled the blood of 52 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 124.32 µg/l and an SD of 37.74 µg/l; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level concentration of 35 µg/l. Write down the hypotheses that would be appropriate for testing if the police officers appear to have been exposed to a higher concentration of lead. Explicitly state and check all conditions necessary for inference on these data. Test the hypothesis that the downtown police officers have a higher lead exposure than the group in the previous study. Interpret your results in context. Based on your preceding result, without performing a calculation, would a 99% confidence interval for the average blood concentration…

An urban community wants to show that the incidence of breast cancer is higher in their locality than in a neighboring rural area. (PCB levels were found to be higher in the soil of the urban community). If you find that in the urban community 20 out of 200 adult women have breast cancer and that in the rural community 10 out of 150 adult women have it, could you conclude, at a significance level of 0.05, that breast cancer is more prevalent in the urban community?1. The parameter of interest is:2. The hypotheses for this test are:3. The calculated test statistic is:4. The critical region is:5. Draw the critical region (make decision):6. It can be concluded that:
