The adoption of smartphones and social media apps has been much discussed. One aspect of these devices is that students tend to be distracted by their phones during class. A recent survey reported that 86% of 1004 randomly sampled females used their smartphones during class time, compared to 81% of 1009 randomly sampled males.

Research Question: Do these results confirm a higher smartphone usage by females?

1. Check the conditions. a sentence stating how this situation meets each condition.

Randomization
Independent Groups
Success/Failure condition - at least 10 of each (success here means the person uses their smartphone in class)

2. State the Hypotheses for a difference of proportions among groups (use a one-tailed test here since the question asks about higher smartphone use by females)

3. Test the hypotheses using a two-proportion z-test. Using technology, give the z-statistic and the p-value.

4. State your conclusion. a sentence that explains whether you reject or fail to reject the null hypothesis. After stating your conclusion, a sentence or two explaining why your decision makes sense in this situation. Then, answer the research question above in simple, everyday language.
