Based on a study, the average elapsed time between when a user navigates to a website on a mobile device until its main content is available was 14.6 seconds. This is more than a 20% increase from the previous year. Responsiveness is certainly an important feature of any website and is perhaps even more important on a mobile device. What other web design factors need to be considered for a mobile device to make it more user friendly? Among other things, navigation menu placement and amount of text entry required are important on a mobile device.

Question
Transcribed Image Text:Based on a study, the average elapsed time between when a user navigates to a website on a mobile device until its main content is available was 14.6 seconds. This is more than a 20% increase from the previous year. Responsiveness is certainly an important feature of any website and is perhaps even more important on a
mobile device. What other web design factors need to be considered for a mobile device to make it more user friendly? Among other things, navigation menu placement and amount of text entry required are important on a mobile device. Suppose the following data provide the time (in seconds) it took randomly selected students
(two for each factor combination) to perform a prespecified task with the different combinations of navigation menu placement and amount of text entry required.

State your conclusion about factor A.
ⒸBecause the p-value > α = 0.05, factor A is not significant.
O Because the p-value > a = 0.05, factor A is significant.
O Because the p-value ≤ α = 0.05, factor A is not significant.
O Because the p-value ≤ α = 0.05, factor A is significant.
