1. An experimental study was conducted by a researcher to determine if a new time slot has an effect on the performance of pupils in mathematics. Fifteen randomly selected learners participated in the study. Toward the end of the investigation, a standardized assessment was conducted. The sample mean was 85 and the sample standard deviation is 3. In the standardization of the test, the mean was 75 and the standard deviation was 10. Based on the evidence at hand, is the new time slot effective? Use 0.05 level of significance
