A computer scientist is investigating the usefulness of two different design languages in improving programming tasks. Twelve expert programmers who are familiar with both languages are asked to code a standard function in both languages and the time (in minutes) is recorded. The data follow: Time Programmer DL 1 DL 2 1 17 18 2 16 14 3 21 19 4 14 11 5 18 23 6 24 21 7 16 10 8 14 13 9 21 19 10 23 24 11 13 15 12 18 20 Find a 95% confidence interval on the difference in mean coding times. Is there any indication that one design language is preferable? O a. -1.216 Hd ≤ 2.55. Because zero is not contained within this interval, one cannot conclude that one design language is preferable at a 1% significance level b. -1.216 M S 2.55. Because zero is contained within this interval, one cannot conclude that one design language is preferable at a 5% significance level Oc. -1.216 ≤ Ha ≤ 2.55. Because zero is not contained within this interval, one can conclude that one design language is preferable at a 5% significance level O d. None among the choices
