10 There are four radio stations in Midland. The stations have different formats (hard rock, classical, country and western, and easy listening), but each is concerned with the number of minutes of music played per hour. From a sample of 10 hours from each station, the following sample means were offered: X1 = 51.46 X2 = 44.68 X3 = 48.23 X4 = 50.67 SS total = 556.000 oints a. Determine SST.

Develop a 95% confidence interval for the difference in the mean amount of music time between station 1 and station 4. (Negative answer should be indicated by a minus sign. Round the final answers to 3 decimal places.) The 95% confidence interval is between and Is there a difference in the mean amount of music time between station 1 and station 4? Use the 0.05 significance level. There is no difference. *A study of the effect of television commercials on 12-year-old children measured their attention span, in seconds.
