x A ~ 1 hour 11/28 QUESTION 13 . 1 POINT A school district has a standardized test that it uses to sort students into magnet schools, where the test is on a 200-point scale. The superintendent's office wants to determine whether male and female students have approximately equal scores on the test. The accompanying table contains scores for a random sample of 10 male students and 10 female students. Assume that the population standard deviation of scores is 20 points for both male and female students, and assume that the scores are normally distributed for both male and female students. Let the male students be the first sample, and let the female students be the second sample. At the 0.05 level of significance, is there evidence that male and female students have different scores, on average? Perform the test using a TI-83, TI-83 Plus, or TI-84 calculator. Find the test statistic, rounded to two decimal places, and the p-value, rounded to three-decimal places. Male Score Female Score 142 122 14 106 61 127 98 147 25 122 140 121 99 125 130 119 156 149 89 113 Provide your answer below: z =], p-value =
