Scenario B. A researcher is interested in studying whether a new app can help improve first graders' reading skills. She recruits two first grade classes from a local elementary school: classroom 1 uses the app for 30 minutes each day and classroom 2 does not use the app. She compares their reading ability at the end of the school year and expects reading ability to improve in the group that used the app. What is the alternative hypothesis for this scenario?

Scenario B. A researcher is interested in studying whether a new app can help improve first graders' reading skills. She recruits two first grade classes from a local elementary school: classroom 1 uses the app for 30 minutes each day and classroom 2 does not use the app. She compares their reading ability at the end of the school year and expects reading ability to improve in the group that used the app. What would be a type I error for this scenario? The researcher concludes that reading skills were the same for the group that used the app and for the group that did not use the app, when in reality the reading skills were the same for both groups. O The researcher concludes that reading skills were higher (better) for the group that used the app than for the group that did not use the app, when in reality the reading skills were the same or worse for the kids who used the app. The researcher concludes that reading skills were the same for the group that used the app and for the group that did not use the app, when in reality the reading skills were better for the kids who used the app. The researcher concludes that reading skills were higher (better) for the group that used the app. than for the group that did not use the app, when in reality the reading skills better for the group that used the app.
