Pleаse nоte thаt this questiоn cоnsists of five pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. A software company developed a spell-check program that correctly identifies spelling errors 86% of the time. A user runs the spell-check program on 12 randomly selected documents with an error. Let X be the number of documents where the spell-check program correctly detects an error. What is the distribution of X? Clearly state the parameters of the distribution. Write down the probability mass function f(x) for the distribution of X. That is, write the probability mass function specific for the random variable of interest in this problem, not just the general formula. What is the probability that the spell-check program correctly detects an error in exactly 9 documents? What is the probability that the spell-check program correctly detects an error in at most 10 documents? Would it be unusual if the spell-check program correctly detects an error in all 12 documents? Show any calculation relevant to your answer.

Just giving the answer without adequate work/explanation may result in zero for the question. A university wants to compare the proportion of graduate students and undergraduate students who had an internship last summer. A random sample of 200 undergraduate students and 85 graduate students was surveyed. Among the 200 undergraduate students, 102 reported having an internship. And among the 85 graduate students, 50 reported having an internship. Give a point estimate for the difference in population proportions of undergraduate and graduate students who had an internship. Set up appropriate null and alternative hypothesis for testing if the population proportion of undergraduate students who had an internship is lower than the population proportion of graduate students who had an internship. What conditions need to be satisfied in order for you to continue with the hypothesis test in part 2? Are they satisfied? Calculate the test statistic for the test you set up in part 2. You may use MINITAB to get the final test statistic. However, you need to show the mathematical calculation that resulted in the final answer. Give the rejection region for this problem. Use 5% significance level. Write the final conclusion in the context of the problem.
If the Weighted Exаm Averаge оf 78% is nоt аchieved, this will be cоnsidered the Total (Weighted Course Total) and the Weighted Exam Average will be posted as the final grade for the course. Assignments will not be included in this calculation. If the Weighted Exam Average of 78% is achieved, then assignments are added to the score and this score will be considered the Total (Weighted Course Total). This score will be posted as the final grade for the course. It must be 78% or above to be considered passing.
