According to information on a granola raisin bran cereal box, the cereal is packaged in boxes containing 18.0 oz. of cereal, with a range (Standard Deviation) of 0.5 0z. Assume that a quality assurance investigator pulls out a random sample of 32 boxes of this cereal and weighs the boxes' contents. Here are the results: 17.3 16.9 18.2 17.4 17.3 18.0 16.8 17.4 18.2 17.8 18.4 16.6 17.3 17.8 17.3 17.7 18.6 17.9 16.5 16.9 17.5 18.3 17 17 18.3 16.8 17.2 17.6 18.2 17.1 18.1 17.5 The company wants to be 95% sure that the cereal boxes are honestly delivering the reported 18 oz of cereal in each box, understanding there will be some variation. Is this true? State the null and alternative hypothesis State the alpha State the decision rule Calculate the statistic State the results To answer this you need to first know the mean of the sample. Then, use the z-test formula to determine the z score of the sample mean. You also need to know the critical number for a two tailed statistical test that rejects the null.

A college entrance exam company determined that a score of 23 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 200 students who completed this core set of courses results in a mean math score of 23.8 on the college entrance exam with a standard deviation of 3.6. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 23 on the math portion of the exam? Complete parts a) through d) below. Click the icon to view the table of critical t-values. a) State the appropriate null and alternative hypotheses. Fill in the correct answers below.

A college entrance exam company determined that a score of 23 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 23.7 on the college entrance exam with a standard deviation of 3.7. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 23 on the math portion of the exam? Complete parts a) through d) below. b) Verify that the requirements to perform the test using the t-distribution are satisfied. Check all that apply. A. The students were randomly sampled. B. The students' test scores were independent of one another. C. The sample size is larger than 30. D. None of the requirements are satisfied.
Dr. Graham is interested in determining if middle-aged adults use text messaging more or less frequently than the general population. Dr. Graham collects information on text messaging from a random sample of 50 adults ages 25 to 44. Dr. Graham finds that these individuals send or receive an average of 68 text messages per day. Using the population mean (and standard deviation) of 41.5 texts per day (34 texts per day), determine whether adults in this age group use text messaging more than the general public.
