MATU 203 BU Verizon & AT&T Hypothesis Test Airport Speeds Excel Worksheet & Discussion
Using technology (StatCrunch, Statdisk, or Excel) compute the mean data speed for each of the two carriers, Verizon and AT&T. Provide a printout of your technology output using the Insert/Edit Image feature (no attachments!) Based on this, which carrier do you think has the faster speed?Next, using technology (StatCrunch, Statdisk, or Excel) conduct a hypothesis test to test your claim about which carrier has the faster speed. Explain which test you conducted and why that is the appropriate test for this example. Provide a printout of your technology output using the Insert/Edit Image feature (no attachments!) Explain your conclusion in statistical and non-statistical terms and how you arrived at that conclusion. Be sure to follow the 8-step procedure on page 360, using technology to do your calculations. You should include your null and alternative hypothesis (in English and in symbolic form), your significance level, whether you are conducting a right tailed, left tailed, or two tailed test, p-value, and conclusions.

He is not confident in his ability to answer some of the problems posed in the course.As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test. Instead, you will be providing a step-by-step breakdown of the problems including an explanation on why you did each step and using proper terminology.What to SubmitTo complete this assignment, you must first download the word document, and then complete it by including the following items on the worksheet:Incorrect AnswersCorrect any wrong answers.

Using these data, construct limits for x- and R- charts.
Small boxes of NutraFlakes cereal are labeled “net weight 10 ounces.” Each hour, random samples of size n = 4 boxes are weighed to check process control. Five hours of observations yielded the following: Weight Time Box 1 Box 2 Box 3 Box 4 9 A.M. 9.8 10.4 9.9 10.3 10 A.M. 10.1 10.2 9.9 9.8 11 A.M. 9.9 10.5 10.3 10.1 Noon 9.7 9.8 10.3 10.2 1 P.M. 9.7 10.1 9.9 9.9 Using these data, construct limits for x- and R- charts. Is the process in control? What other steps should the QC department follow at this point?

<p>Conclusion: More education causes a person's income to rise.</p>
Is the following conclusion drawn after finding that there is a significant correlation between annual personal income and years of education true?Conclusion: More education causes a person's income to rise. The conclusion cannot be drawn because correlation does not necessary implies causality. The conclusion is correct since the correlation is significant. The conclusion is incorrect; Instead we should conclude that annual personal income increases more years of education.

MATU 203 BU Verizon & AT&T Hypothesis Test Airport Speeds Excel Worksheet & Discussion
Using technology (StatCrunch, Statdisk, or Excel) compute the mean data speed for each of the two carriers, Verizon and AT&T. Provide a printout of your technology output using the Insert/Edit Image feature (no attachments!) Based on this, which carrier do you think has the faster speed?Next, using technology (StatCrunch, Statdisk, or Excel) conduct a hypothesis test to test your claim about which carrier has the faster speed. Explain which test you conducted and why that is the appropriate test for this example. Provide a printout of your technology output using the Insert/Edit Image feature (no attachments!) Explain your conclusion in statistical and non-statistical terms and how you arrived at that conclusion. Be sure to follow the 8-step procedure on page 360, using technology to do your calculations. You should include your null and alternative hypothesis (in English and in symbolic form), your significance level, whether you are conducting a right tailed, left tailed, or two tailed test, p-value, and conclusions.

He is not confident in his ability to answer some of the problems posed in the course.As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test. Instead, you will be providing a step-by-step breakdown of the problems including an explanation on why you did each step and using proper terminology.What to SubmitTo complete this assignment, you must first download the word document, and then complete it by including the following items on the worksheet:Incorrect AnswersCorrect any wrong answers. You must also explain the error performed in the problem in your own words.Partially Finished WorkComplete any partially completed work. Make sure to provide step-by-step instructions including explanations.Blank QuestionsShow how to complete any blank questions by providing step-by-step instructions including explanations.Your step-by-step breakdown of the problems, including explanations, should be present within the word document provided. You must also include an Excel workbook which shows all your calculations performed.

Using these data, construct limits for x- and R- charts.
Small boxes of NutraFlakes cereal are labeled “net weight 10 ounces.” Each hour, random samples of size n = 4 boxes are weighed to check process control. Five hours of observations yielded the following: Weight Time Box 1 Box 2 Box 3 Box 4 9 A.M. 9.8 10.4 9.9 10.3 10 A.M. 10.1 10.2 9.9 9.8 11 A.M. 9.9 10.5 10.3 10.1 Noon 9.7 9.8 10.3 10.2 1 P.M. 9.7 10.1 9.9 9.9 Using these data, construct limits for x- and R- charts. Is the process in control? What other steps should the QC department follow at this point?

<p>Conclusion: More education causes a person's income to rise.</p>
Is the following conclusion drawn after finding that there is a significant correlation between annual personal income and years of education true?Conclusion: More education causes a person's income to rise. The conclusion cannot be drawn because correlation does not necessary implies causality. The conclusion is correct since the correlation is significant. The conclusion is incorrect; Instead we should conclude that annual personal income increases more years of education.
