A soap manufacturing company was distributing a particular brand of soap through a large number of retail shops. Before a heavy advertisement campaign, the mean sales per week was 140 dozens. After the campaign, a sample of 26 shops was taken and the mean sales was found to be 147 dozens with standard deviation 16. Perform a statistical test to check the advertisement effectiveness. If the tabulated value of the test statistic (with 25 df) corresponding to upper 5% is 1.708, then what will be your conclusion?
