Fast computer: Two microprocessors are compared on a sample of 6 benchmark codes to determine whether there is a difference in speed the times (in seconds) used by each processor on each code are as follows: Code 3 4 Processor A 24.8 17.3 25.0 18.1 27.7 22.8 Processor B 27.8 16.3 22.3 26.5 25.4 26.6 Send data to Excel Part: 0 / 2 Part 1 of 2 (a) Find a 99.9% confidence interval for the difference between the mean speeds. Let d represent the speed of processor A minus the speed of processor B. Use tables to find the critical value. Carry your intermediate computations to at least 3 decimal places.

A CBS News poll conducted June 10 and 11, 2006, among a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results are shown in the table below. better same worse Republican 38 104 44 Democrat 12 87 137 none 21 90 118 Express each of your first five answers as a decimal and round to the nearest 0.001 (in other words, type 0.123, not 12.3% or 0.123456). What fraction of survey respondents identified themselves as Democrats? What fraction of survey respondents thought the economy was getting better? What fraction of Democrats thought the economy was getting better? Among survey respondents who thought the economy was getting better, what fraction were Democrats? What fraction of survey respondents were Democrats who thought the economy was getting better? The three pie charts below show the opinions about…
Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 245 men, 70 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 170 women, 62 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is less than the proportion of women with elevated cholesterol levels? Let p₁ denote the proportion of men with elevated cholesterol levels and p₂ denote the proportion of women with elevated cholesterol levels. Use the a= 0.05 level of significance and the P-value method with the TI-84 Plus calculator.

Many graduate school programs in the United States require applicants to take the Graduate Record Exam, also called the GRE. One part of the exam, the GRE-Quantitative test, assesses students' level of quantitative reasoning and thinking - exactly the skills we are building in our class this semester. The highest score possible on the GRE-Quantitative test is a score of 800. Many graduate schools think that a score of 700 or higher on the GRE-Quantitative test shows that the applicant has strong quantitative skills. The table shows the number of people who took the GRE between 2003 and 2006 who had GRE-Quantitative test Scores of 700 or higher. All of the people represented in the table planned to major in one of the two listed areas of the social sciences. a. Complete the table.

A researcher is conducting a test to see if handedness (right or left) affects the speed at which people perform a particular task. The researcher only knows the order in which the contestants finished. When the data are summarized (with R for right-handed and L for left-handed) the order of finishing (fastest to slowest) was: R, R, R, R, L, R, L, R, L, L Is there statistically significant evidence of an effect of handedness on the speed? Test statistic: The name of the statistical table, degrees of freedom (if appropriate), and the numerical value of the critical value for this test: P-value: Circle an appropriate conclusion: • There is significant evidence that left-handed contestants will finish the task faster. • We cannot reject the hypothesis that handedness has no effect on the time to finish the task. • There is significant evidence that right-handed contestants will finish the task faster.
The director of student recruitment is interested in the ACT scores for the incoming Freshmen class. A group of 300 students is surveyed and the research finds that these students have an average ACT score of 21. For this study, the average of 21 is an example of a(n) ___________.
