Sets of 10 randomly selected students take a reading comprehension test with rock, country-western, or classical music in the background. The results are as follows (higher scores reflect better comprehension): READING COMPREHENSION SCORES ROCK (1) COUNTRY-WESTERN (2) CLASSICAL (3) 90 99 52 11 94 75 82 95 91 67 23 94 98 72 97 93 81 31 73 79 83 90 28 85 87 94 100 84 77 69 Why might the H test be preferred to the F test for these data? Use H to test the null hypothesis at the .05 level of significance.
