Random samples of 100 scientists, 100 journalists and 100 government officials were asked about the safety of nuclear power plants. Responses were made on a seven point scale, where 1=very unsafe and 7=very safe. The mean safety scores for the groups are scientists, 4.1; journalists, 3.7; government officials, 4.2 a) Identify the response variable for this study b) How many treatments are included in this study? Describe them. c) Specify the null and alternative hypothesis tht should be used to investigate whether there are differences in the attitudes of scientists, journalists and government officials regarding the safety of nuclear power plants. d) The MSE for the sample data is 2.355. At least how large must MST be in order to reject the null hypothesis of the test of part a) using a level of significance of .05 e) If the MST = 11.280, what is the approximate p-value of the test of part a)? . -- Jay Warner Principal Scientist Warner Consulting, Inc. 4444 North Green Bay Road Racine, WI 53404-1216 USA Ph: (262) 634-9100 FAX: (262) 681-1133 email: [EMAIL PROTECTED] web: http://www.a2q.com The A2Q Method (tm) -- What do you want to improve today? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
