You may need to use the appropriate appendix table or technology to answer this question. Suppose that a recent issue of a magazine reported that the average weekly earnings for workers who have not received a high school diploma is $494. Suppose you would like to determine if the average weekly for workers who have received a high school diploma is significantly greater than average weekly earnings for workers who have not received a high school diploma. Data providing the weekly pay for a sample of 50 workers are available in the file named WeeklyHSGradPay. These data are consistent with the findings reported in the article. Weekly Pay 687.73 543.15 789.45 442.26 684.85 661.43 478.3 629.62 486.95 786.47 652.15 652.82 669.81 641.13 577.24 845.68 541.59 553.36 743.25 468.61 821.71 757.82 657.34 506.95 744.93 553.2 827.92 663.85 685.9 637.25 530.54 515.85 588.77 506.62 720.84 503.01 583.18 7,980.24 465.55 593.12 605.33 701.56 491.86 763.4 711.19 631.73 605.89 828.37 477.81…

According to a los angeles times study of more than 1 million medical dispatches from2007 to 2012, the 911 response time for medical aid varies dramatically across LosAngeles (la times website, November 2012). Under national standards adopted by theLos Angeles Fire Department, rescuers are supposed to arrive within six minutes to almostall medical emergencies. But the times analysis found that in affluent hillside communities stretching from griffith Park to Pacific Palisades, firefighters failed to hit that marknearly 85% of the time.The following data show the response times, in minutes, for 10 emergency calls in thegriffith Park neighborhood.11.8 10.3 10.7 10.6 11.5 8.3 10.5 10.9 10.7 11.2Based on this sample of ten response times, compute the descriptive statistics in parts (a)and (b) and then answer the questions in parts (c) and (d):a.

To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow. Adjusted Gross Income($1,000s) Itemized Deductions($1,000s) 22 9.6 27 9.6 32 10.1 48 11.1 65 11.5 85 19.7 120 23.5 (a) Develop a scatter diagram for these data with adjusted gross income as the independent variable. A scatter diagram has 7 points plotted on it. The horizontal axis ranges from 0 to 140 and is labeled: Adjusted Gross Income ($1,000s). The vertical axis ranges from 0 to 30 and is labeled: Itemized Deductions ($1,000s). The points are…
