The researchers were interested in seeing if men (2) spent more time on their personal computer than women (1). For this hypothesis (Ho: mu2 - mu1 = 0 vs. Ha: mu2 - mu1 > 0), the p-value was 0.0169. Interpret. "With a p-value of 0.0169, the researcher has [word1] statistically significant evidence that the [word2] mean of men who spend time on their personal computer per week is [word3] than women"
