- You have conducted a series of experiments to reduce the proportion of scrapped battery cells to 1% in your manufacturing plant. What is the probabilty of testing 51 cells without finding a defect until the last cell?Can you solve this problem about the confidence interval?Come up with your own data for a problem that would ask for a 90% confidence interval utilizing Z. Clearly label your variables.
- Suppose we take a sample of 2,500 blood donors from a population for which 50% (0.5) have type O+ blood. (a) Into what range of possible values should the sample proportion fall 95% of the time, according to the Empirical Rule? to (b) If the sample included only 625 donors instead of 2,500, would the range of possible sample proportions be wider, more narrow, or the same as with a sample of 2,500 donors? Explain your answer, and explain why it makes intuitive sense. The range would be with 625 donors compared to a sample of 2,500 donors since the standard deviation of the sampling distribution would be . This makes intuitive sense because if fewer donors are included in the sample, the proportion will be reliable as an estimate of the proportion.Suppose you have a population of 450 housewives and you want to know their preference for a toothpaste. It is intended to interview only a sample to find out if they use it. What should be the minimum sample size that meets with a standard error of 0.04 and a reliability of 85%?Low-income students tend to have lower attendance rates and lower math test scores than their middle/upper income peers. Would raising their attendance close the achievement gap? To explore this possibility, a random sample was collected of students in a local school district. For each student, data was collected on their attendance rate (percent of school days attended) and raw test scores on the Algebra 1 state exam. The superintendent of the district asks: “If a student meets our minimum attendance goal (87%), what would their predicted test score be?” In order to answer this question, we first need to find the equation of the least squares regression line. This involves multiple parts, including the slope and intercept. Percent Attendance (x) STAAR Algebra 1 Raw Score (y) 95 45 82 49 61 37 Find the slope for the equation of the least squares regression line: A. 0.5.

- What would you conclude based on an α=0.05 level? We reject the null hypothesis and do not accept the alternative hypothesis since there is sufficient evidence that the proportion of all vehicles that meet or exceed current fuel economy standards is greater than 90% due to the p-value being greater than the α level. Explain the results of your hypothesis test. What does the p-value signify? Would you say the observed outcome was unusual? If so, how unusual was the outcome?A limousine company is concerned with increasing costs of maintaining their fleet of 150 cars. After testing, the company found that the emissions systems of 9out of the 20 cars they tested failed to meet pollution control guidelines. They had forecasted costs assuming that a total of 54cars would need updating to meet the latest guidelines. Is this strong evidence that more than 36% of the fleet might be out of compliance? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. What are the null and alternative hypotheses? What is the value of the test statistic? What is the P-value of the test statistic? What is your conclusion?A large trucking company wants to estimate the proportion of its trailer truck population with refrigerated carrier capacity. A random sample of 200 trailer trucks is taken and 30% of the sample have refrigerated carrier capacity. The 90% confidence interval to estimate the population proportion is?
- You are working for an adoption agency and want empirical support for the idea that early adoption (at birth) leads to better outcomes relative to later adoption (after age 3 years).
