A community college employs 86 full-time faculty members. To gain the faculty's opinions about an upcoming building project, the college president wishes to obtain a simple random sample that will consist of 9 faculty members. He numbers the faculty from 1 to 86. Complete parts (a) and (b) below. Click the icon to view the random number table. ..... (a) Using the provided random number table, the president closes his eyes and drops his ink pen on the table. It points to the digit in row 3, column 6. Using this position as the starting point and proceeding downward, determine the numbers for the 9 faculty members who will be included in the sample. The numbers for the faculty members are (Use a comma to separate answers as needed.) (b) The president uses technology to produce the following random numbers. 15 34 60 79 62 34 44 27 2 32 Determine the numbers for 9 faculty members who will be included in the sample. The numbers for the faculty members are (Use a comma to separate answers as needed.)
