A professor observed the number of times mobile phones interrupted the signal of her microphone during her lecture. She did this for 10 randomly selected lectures before and after issuing a warning to confiscate mobile phones during class. Software Output: Shapiro-Wilk Test data: paired_differences_counts p-value = <0.0001 Using the test, the p-value resulted to 0.1063. Based on this, what is the appropriate conclusion? a. There is evidence that the average number of interruptions due to mobile phones decreased after issuing a warning to the class. b. There is no evidence that the average number of interruptions due to mobile phones decreased after issuing a warning to the class
