In a pattem recognition study, the participants were asked to examine a picture and see if they could recognize a word. The picture contained the word "technology written backwards. A total of 11 librarians and 13 designers succeeded in recognizing the word. The times taken (in seconds) for the successful participants recognized the word were as follows. Librarians Designers 55 18 99 54 87 11 62 68 27 90 57 23 69 34 31 30 31 27 51 29 45 42 48 74 a) Test the hypothesis that the variability of times taken for librarians exceeds the times taken for designers at 5% level of significance. b) Construct a 95% confidence interval for the mean of times taken by librarians. Interpret the interval obtained.
