**For their final project, a group of Statistics students investigated their belief that females text more than males. They asked a random sample of students from their school to record the number of text messages sent and received over a one-day period. Here are the data:**| | | | | | | | | | | ||--------|------------|------------|------------|------------|------------|------------|------------|------------|------------|------------|| **Males** | 83 | 124 | 61 | 23 | 24 | 126 | 56 | 30 | 127 | 34 | 26 | 12 || **Females** | 76 | 121 | 71 | 47 | 60 | 173 | 24 | 83 | 52 | 41 | 34 | 169 | 23 | 85 | 20 |**c. Compare the distributions.**The students aim to determine whether the distribution of text message usage is higher among females than males based on the sample data collected. The analysis should consider both the number of texts sent and received.[An image showing a table of data for text messages sent and received by males and females.]In summary, this information highlights the project conducted by statistics students to analyze text message patterns and compare the distributions between male and female students.
