Grades on a standardized test are known to have a mean of 1030 for students in the United States. The test is administered to 435 randomly selected students in Florida; in this sample, the mean is 1043.39 and the standard deviation (3) is 111.24. The 95% condence interval for the average test score for Florida students is ( 1032.94 , 1053.84 ). (Round your responses to two decimal places.) Is there statistically signicant evidence that Florida students perform differently than other students in the United States? The 95% condence interval for the average test score for Florida students V ,4 = 1030, so the null hypothesis that y = 1030 (that Florida students have the same average performance as other students in the United States) V at the 5% level
