A researcher claims that NSU students spend 3.5 hours on average a day browsing

facebook when not in lockdown. However, your instructor disagrees with the

researcher. Your instructor assumes that NSU students, under normal circumstances,

spend more than 3.5 hours per day on facebook.

The instructor took a simple random sample of 49 NSU students and found that these

49 students spent an average of 4.1 hours a day browsing facebook. The standard

deviation of these 49 students is 2.1 hours. Using the critical-value approach, what

is your conclusion about the instructor's assumption given 1% significance level?
