Pass rates for Intermediate Algebra at a community college are 53.6%.  In an effort to improve the course, faculty of a community college develop a mastery-based learning model where course content is delivered is through a computer program.  The instructor serves as a learning mentor for the students in the course.  Of the 480 students who enrolled on the mastery-based course, 275 did pass.  At the 0.05 level of significance, decide whether the sample evidence suggests that the mastery-based learning model improved pass rates. a. What is your hypotheses (see above choices) b.  What is your test statistic? c.  What is your p-value or critical values and what is your conclusion? Briefly explain as in, I reject Ho because….. or I do not reject Ho because….. d.  Write a conclusion sentence in the context of the problem. e.  What type of error could you have made? Briefly explain.

If the 95% confidence interval for the mean cost of texts books per semester at a community college is between ($145, $645), what would be the appropriate conclusion sentence. a.  There is a 95% probability the mean cost of the textbooks at a community college are between $145 and $645. b.   We are 95% confident the mean cost of the textbooks at a community college are between $145 and $645. c.  There is a 95% chance the mean cost of the textbooks at a community college are between $145 and $645. d.   The the mean cost of the textbooks at a community college are between $145 and $645. Answer: [answer1]   Based on the above confidence interval would it be unusual for a student to spend $500 on textbooks for one semester at a community college? a.  No, because textbooks are expensive and who knows what you will spend. b.  Yes, because $500 is outside of the bounds for the 95% confidence interval and that would make spending $500 unusual. c.  No, because $500 is within of the bounds for the 95% confidence interval and that would make spending $500 usual. d.  Yes because $500 is within the bounds of the 95% confidence interval and that would make spending $500 unusual. Answer: [answer2]

Twelve jurors are randomly selected from a large population in which it is known that 85% are right handed. Assuming the jury has 12 members, find the following: (you may round your answers to 4 decimal places, no sentence necessary) a. Find the probability that exactly 6 are right handed. [answer1] b. Find the probability that at most 6 of them are right handed. [answer2] c. Find the probability that at least 6 of them are right handed.  [answer3]

An environmentalist wanted to determine of the mean acidity of rain differed among Alaska, Florida, and Texas.  18 randomly selected six rain dates of each of the three locations and obtained the following data: Alaska Florida Texas 5.41 4.87 6.46 5.39 5.18 6.89 4.90 4.52 6.57 5.14 5.12 4.15 4.80 4.89 4.45 5.24 5.06 4.30   Test whether the acidity of the rain is the same in the three cities, use a 0.05 significance level.  You may assume the requirements are met to run this test. a. What are the null and alternative hypotheses? b.  What is your test statistic? c.  What is your p-value or critical values and what is your conclusion? Briefly explain as in, I reject Ho because….. or I do not reject Ho because….. d.  Write a conclusion sentence in the context of the problem.
