The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states, where xx is thousands of automatic weapons and yy is murders per 100,000 residents. xx 11.3 8.2 7.1 3.7 2.9 2.2 2.1 0.6 yy 13.9 10.7 10.3 7.2 6.5 5.6 5.5 4.6 Use your calculator to determine the equation of the regression line and write it in the y=ax+by=ax+b form. Round to 2 decimal places. According to this model, how many murders per 100,000 residents can be expected in a state with 4.6 thousand automatic weapons? Round to 3 decimal places. According to this model, how many murders per 100,000 residents can be expected in a state with 4.4 thousand automatic weapons? Round to 3 decimal places.
What does this data tell you? Section 4 appears to be a challenge; remember you must compare data to the national data and determine if there are any statistically significant differences at the 0.5 level. For Table 4-1, Information for national is given in table 4-4. You must then comment if it is statistically significant. For table 4-2 and 4-3 you can use formulas with data from table 4-4 (hints below) to find the national and comment if it is statistically significant. Here is a hint: Table 4-2: National Medicare Reimbursement/National Number of Discharges = Average National Reimbursement Hope that helps! Let me know if you have any questions. Table 4-1 Average Length of Stay (ALOS) Average Length of Stay (ALOS) DRG Hospital National Statistically Significant 088 4.6 5.0 (5.0-4.6 = 0.4 0.5) Yes (4.7 3.6 = 1.1 > 0.5) Yes (8.2-7.9 = 0.3 <0.5) No (7.4 -7.3 = 0.1< 0.5) No Table 4-2 Average Charges Average Charges DRG Hospital National Statistically Significant 088 $13,952 14,208…

You may need to use the appropriate appendix table or technology to answer this question. A national standardized test consists of three parts: critical reading, mathematics, and writing. Suppose each part of the test is scored on a 200- to 800-point scale with a median of approximately 510. Scores for each part of the test can be assumed to be symmetric. Use the following data to test the hypothesis that the population median score for the students taking the writing portion of the test is 510. 635 701 439 447 464 502 405 453 471 476 447 590 337 387 514 State the null and alternative hypotheses. O Ho: Median # 510 H₂: Median = 510 O Ho: Median 2 510 H₂: Median 510 ✓ Find the value of the test statistic. T = Find the p-value. (Round your answer to four decimal places.) p-value = Using a = 0.05, what is your conclusion? O Reject Ho. There is sufficient evidence to conclude that the population median writing test score is not 510. Ⓒ Do not reject Ho. There is not sufficient evidence to…
Johnson Filtration, Inc., provides maintenance service for water-filtration systems throughout southern Florida.
