A study is conducted to compare the frequency of texting between high school students and college students. 9 high school students and 9 college students are independently and randomly selected. These students are asked to record how many texts they send the next day. The results are below. Test the hypothesis that there is a difference in the means for the average number of texts sent each day for high school students and college students. H.S. 106 College 95 58 96 150 140 94 70 89 111 112 114 89 99 115 94 135 117 1. Clearly state the hypotheses using correct notation. 2. Name the test you are going to use. 3. Give your test statistic and p-value. 4. Make your decision about the null hypothesis and state your conclusion regarding whether or not there is a significant difference in the mean number of texts sent each day by high school and college students.
