Reseаrch questiоn: Dо mоre thаn 25% of аll World Campus students own wearable technology (e.g., FitBit, Apple Watch)? Data were collected from a representative sample of 400 World Campus students. In that sample, 112 owned wearable technology. Minitab was used to address this research question. 1-Sample Proportion: Wearable Technology Method Event: Wearable Technology = Yes p: proportion where Wearable Technology = Yes Normal approximation method is used for this analysis Descriptive Statistics N Event Sample p 95% Lower Bound for p 400 112 0.280 0.243 Test H0: p = 0.25 Ha: p > 0.25 Z-Value P-Value 1.38 0.0829 Given this output, at the 0.05 alpha level we should [decision] the null hypothesis. There [evidences] that more than 25% of all World Campus students own wearable technology.
