49. Does Multitasking Degrade your neighbor's Performance? Refer to the previous exercise. The same journal article reported that those sitting next to the multitaskers may have also suffered from degraded quiz performance, due to being distracted by their neighbor's laptop multitasking. The following table provides the summary statistics for a class quiz for the two groups: those sitting where they could see the multitasker's screen (multitasker's neighbors), and those who could not (multitasker's non-neighbors). Test whether the population mean score for the multitasker's neighbors is lower than that of the multitasker's non-neighbors, using level of significance .
