It turns out that the difference is in the methodology of data collection (Reynolds, 2020). In the 2016 research, people were asked to recall their activity and sedentary time. Unfortunately, humans are unreliable in narrating their life. They tend to overestimate their physical activity and underestimate their sedentary time. In the 2020 research, many authors of the 2016 reviews decided to repeat the study but with the participants wearing activity monitors. This research provided a more accurate result which was drastically different from the earlier report.

Being a sharp student in Statistics, you picked up on the important point of accurate data collection methodology. You decided to try it out on your course mates. Initially, you have asked 100 course mates to give an estimate of their average sedentary time in a day. Thereafter, you asked them to wear an activity monitoring device and calculated their average daily sedentary time objectively. The recordings were found in the dataset provided.

Examine how humans tend to report their sedentary time by using the data given and

applying at least two (2) inferential statistical methods.

Is this a one-tailed hypothesis test or a two-tailed hypothesis test? Can help??
