Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. The success of the procedure depends on various biomechanical properties of thehuman nasal periosteum and fascia. An article reported that for a sample of 16 (newly deceased) adults, the mean failure strain (%) was 24.0, and the standard deviationwas 3.4.(a) Assuming a normal distribution for failure strain, estimate true average strain in a way that conveys information about precision and reliability. (Use a 95%confidence interval. Round your answers to two decimal places.)%,(b) Predict the strain for a single adult in a way that conveys information about precision and reliability. (Use a 95% prediction interval. Round your answers to twodecimal places.)%,How does the prediction compare to the estimate calculated in part (a)?O The prediction interval is the same as the confidence interval in part (a).O The prediction interval is much wider than the confidence interval in part (a).O The prediction interval is much narrower than the confidence interval in part (a).

Before accepting a large shipment of bolts, the director of an elevator construction project checks The tensile strength of a simple random sample consisting of 20 bolts. She is concerned that the bolts may be counterfeits, which bear the proper markings for this grade of bolt, but are made from inferior materials. For this application, the genuine bolts are known to have a tensile strength that is normally distributed with a mean of 1400 pounds and a standard deviation of 30 pounds. The mean tensile strength for the bolts tested is 1385 pounds. Formulate and carry out a hypothesis test, using the critical value approach and at a 3% level of significance to examine the possibility that the bolts in the shipment might not be genuine. Be sure to show all the steps of this approach i.e..i. state H0 and HA, ii. select α, select the test statistic (giving reason for your choice) and compute it, iii. get the critical value, iv .compare the test statistic, v. state your decision, and vi.…
An ambulance service located at the edge of town is responsible for serving a large office building in the down- town area. Testing different routes for getting from the ambulance station to the office building, a driver finds that five trips using route A take an average of 5.9 minutes, with a standard deviation of 1.4 minutes; six trips using route B take an average of 4.2 minutes, with a standard deviation of 1.8 minutes. Assuming normal populations with equal standard deviations, and using the 0.10 level, is there a significant difference between the two routes? a)Define Null and alternative hypotheses a)Using a 5% level of significance, test to determine A route timing mean is higher than the B mean. Describe the findings in terms of the problem.
A company which produces batteries claims that the life expectancy of their batteries is at least 90 hours. Totest the claim, a consumer interest group tested a random sample of 40 batteries. The test resulted to a mean life expectancy of 87 hours. Using a 0.05 level of significance, can it be concluded that the life expectancy of their batteries is less than 90 hours? Assume that the population standard deviation is known to be 10 hours.
Because schools in areas affected by these natural disasters were disproportionately low performing schools, many students affected were not only forced to switch schools, but also ended up switching to a higher quality school. Sacerdote finds initial declines in test scores (likely due to the shock of displacement), but “by the third and fourth years after the disaster, evacuees displaced [by these natural disasters] see a 0.18 standard deviation improvement in scores.” Sacerdote also finds that the improvements observed were “concentrated among students initially in the lowest quintiles of the test score distribution.” 1. Define the outcome (Y), the endogenous regressor (X), and the instrument (Z) in the context of this study.2. Is this instrument relevant? Explain why or why not.3. Is this instrument exogenous? Explain why or why not.4. For what group of individuals is this study externally valid? List at least two groups for which this study is unlikely to yield externally valid…
Assuming cholestorol data indicated a mean total cholesterol level for adult persons 20 years of age and older in the United States was 190 mg/dl; with a known standard deviation of 30 mg/dl. Use a known standard deviation of 30 mg/dl and the underlying population is normally distributed. What is the probability that a randomly selected adult, ≥ 20 years of age will have a cholesterol level < 180 mg/dl?
