An e-business/e-commerce information technology consulting company wants to compare the effectiveness of three programming languages that its programmers use. Currently each programming language is used by approximately 1/3 of the company's programmers. The director of the programming division randomly selected five programmers from the users of each of the three programming languages and assigned the same simple programming task to each programmer. All three populations have highly skewed distributions with extreme outliers. The rank sum values for each of the programming groups are T₁ = 23, T₂ = 48, and T₃ = 49. At α = .05, does the median time required to program a simple task differ between the three different programming languages? A) H = 4.34, reject the null hypothesis. B) H = 4.34, do not reject the null hypothesis. C) H = 5.99, reject the null hypothesis. D) H = 5.99, do not reject the null hypothesis.

= 5.99H = − 3(15 + 1) H = 4.34 4.34 < 5.99, failed to reject H₀. It appears that the median time to complete the simple programming task does not significantly differ among the three different programming languages.
