Decide on two variables that you think may show an association (positive or negative) and manually test for an association by doing the following: a. (5) Describe the relation that you want to test. Why do you suspect that the two variables are associated and do you expect this will produce a positive or a negative association? Which variable are you treating as the explanatory variable and which as the response variable (Your later work should conform to this choice)? b. (3) Select a simple random sample of 8 states. Give the list of states and explain carefully and clearly how you selected the states. A table of random numbers is provided which you may use or you can go to random.org and use their random sequence generator, but document it if you do so. C. (12) For your sample, do the following: . (2) Draw a scatterplot of the data. (2) Calculate the linear correlation coefficient, r. 111. (2) Compare the critical value of correlation coefficient and comment on the association iv. (2) Regardless of the correlation coefficient, find the least-squares regression line for your data Code pl Rail 15. 5758 ONE 2 CONS 10 305 175 13 . 2012 To 166 159 14 w DATA FOR PROBLEM 1: Powell Camere Completed Salary 1 ALA 1941 1956 2 AKN w 3 599 4 AR 794 4115 5 CA 07 11.1 CO Code 90.7 3936 3 CT 711 1211 100 DE Dwa 15 HI de 573 1734 10 56 26 11 41 ID 720 35 11 711 14 IN India 2025 3751 15 TA 33 11 16 KS 12 KY by IN LA 5776 5493 5435 1 MI 775 3019 30 MD Mund 10 21 MA Macht 32 MIN MN XLT 2013 34 MSM 10014 3959 MOM 732 54 EMT Me 3114 27 NN 141 NVN 95 TON 161 16 141 9 CE TE 125 163 LIS PUT 15 16 161 141 149 5356 ST LE 739 11 SS IE SI SRL 153 2NImp 10 Now NMN NYNY NC North Care ND North Dako 609 49195 905 TE SE 1 06 411 SO 4710 TOP 4555 45.4 OK 37ORD SPA Richede Band TER 945 9 141 155 151 190 155 1 OS PUNT 3730 65 UT IF SF 2006 UN 17014 IT: 700 619 TE 34763 314 20195 1902 1985 491 26 MOCI ALL STI SH 171 SD katha TN a 41 TX Bees 44 UT 45 VT VA in WW WW 49W SOWY CVT MO SI 29192 101 1560 2 121 125 109 14 TAIT 30 201 T48 70 133 141 67 DATA FOR PROBLEM Previous Next Dashboard Calendar To Do Notifications Inbox
