A psychological researcher was interested in the helping behavior of 3-year-old children. In particular, the researcher wanted to know if the helping behavior of these children differed depending on whether they were monolingual (knows only 1 language) or bilingual (knows 2 languages). They had a group of 109 children and each child was in a room alone with another person who they watched solve a puzzle. The researcher noted whether or not the child helped the person with the puzzle. The data is below. Test at an alpha at 0.05 and use all the steps of hypothesis testing for full marks.
