Help me answer all parts except A&D An economist is studying the job market in Denver area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six Denver neighborhoods gave thefollowing information (units in hundreds of jobs).x1330 50 28 50 25y235 9 3USE SALTComplete parts (a) through (e), given Ex= 196, y = 28, Ex2 = 7478, Ey2 = 164, Exy = 1081, and r = 0.8786.(a) Draw a scatter diagram displaying the data.1515x (total number of jobs (in hundreds))x (total number of jobs (in hundreds))x(total number of jobs (in hundreds)x(total number of jobs (in hundreds))(b) Verify the given sums Ex, Ey, Ex2, Ey2, Exy, and the value of the sample correlation coefficient r.

Write out solutions to the following questions. Show all calculations using the formulas. Include all diagrams appropriately labeled. Use proper notation throughout the solution. Think of the assignment as if you were demonstrating to someone how to do these problems. The quality of the work and the neatness and organization of the work will count in the grade. A random sample of 25 frozen dinners of a certain type was selected from production during a particular period and the calorie content of each one was determined. The resulting observations are: Calories from Frozen Dinners 255 244 239 242 265 245 259 248 225 226 251 233 266 227 246 240 257 222 237 270 230 260 268 231 238 The stated calorie content is 240 calories. At the 5% significance level, do the data suggest that the mean calorie content of the frozen dinners differs from 240 calories? State the null and alternative hypothesis Check the conditions. To determine if the data is approximately normal, using…

Calculate the age standardized IHD mortality rate using the Standard population. Show all calculations. (See attached image) Shouldn't the answer be like this? : Age-specific rate, 0 to 19 years= 11 (number of deaths) ÷ 9043000 (total population) × 40,000= 0.0487 IHD deaths Age-specific rate, 20 to 39 years = 606 (number of deaths) ÷ 12543000 (total population) × 28, 000= 1.35 IHD deaths Age-specific rate, 40 to 59 years= 10,071 (number of deaths) ÷ 11060000 (total population) × 21,000= 19.1 IHD deaths Age-specific rate, 60 to 79 years = 44947 (number of deaths) ÷ 6568000 (total population) × 10,000 = 68.4 IHD deaths Age-specific rate, 80+ years = 28940 (number of deaths) ÷ 779000 (total population) × 1000 = 37.2 IHD deaths MULTIPLYING EACH BY THE STANDARD POPULATION FOR EACH AGE GROUP, NOT MULTIPLYING BY 100,000?? And do we add all the numbers up to get 126 deaths per 100,000 people or do we leave the numbers for each age group as is? Thank you.
