Some jobs require a great deal of dexterity to properly position components intoplace. A large North American computer maker routinely tests applicants for these jobs by giving adexterity test that involves a number of intricate finger and hand movements. The tests are scoredon a 100-point scale. Only those who have scored above 70 are hired. To determine whether the testsare valid predictors of job performance, the personnel manager drew a random sample of 45 workerswho were hired 2 months ago. He recorded their test scores and the percentage of nondefectivecomputers they produced in the last week. Determine the regression line and interpret thecoefficients by using a 5% significance level.

A smartphone manufacturer is so certain of its quality control that it offers a complete replacement warranty if the smartphone fails within 3 years. Based upon compiled data, the company notes that there is a 2 percent chance that its smartphone will fail during the first year, a 10 percent chance that a smartphone that survives the first year fails during the second year, and a 20 percent chance that a smartphone that survives the first two years fails during the third year. The warranty does not cover replacement smartphones after the third year. (a) Formulate the evolution of the status of the smartphone as a Markov Chain whose states include two abosrbing states that involve needing to honor the warranty or having the smartphone survive the warranty period. Construct the transition probability matrix and draw the transition probability diagram. (b) Determine the probability that: (a) the manufacturer will have to honor the warranty and (b) the manufacturer will not…
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.

During the Covid crisis, there were lockdowns and working-from-home, which made collecting data on unemployment more challenging. Researchers from Heriot Watt University conducted a survey of 400 individuals in the labour force to assess rise in unemployment in September 2020. The object was to find out whether the unemployment rate had risen above a benchmark proportion of 6 per cent of the labour force in Malaysia. Of the surveyed persons, 34 reported being unemployed in the week prior to the survey. Conduct a two-tailed test of whether unemployment rate during this period was 6 per cent. Set out your null and alternative hypotheses, significance level, test statistic, assumptions and sampling distribution clearly. Conduct the test and comment on the economic significance of the findings
