To answer your question accurately regarding the statements about range and mean, I would need the specific data from the line plots showing the hours spent reading by boys and girls. However, I can guide you on how to interpret the data to make these comparisons.
1. **Range**: The range is calculated by subtracting the minimum value from the maximum value for each group (boys and girls).
- If the range for the girls is greater than that for the boys, you would choose the first option: "A) The range is greater for the girls, B) The mean is less for the girls" or any option stating that the range is greater for the girls.
- Conversely, if the boys have a greater range, you would select the option that states this.
2. **Mean**: The mean is calculated by adding all the values for each group and dividing by the number of observations (which is 10 for each group in this case).
- If the mean hours reading for girls is higher than for boys, you would choose the option stating that the mean is greater for girls.
- If boys have a greater mean value, select the option that indicates this.
To conclude, review the data provided in the line plots for both boys and girls to determine their range and mean. Compare the calculated values to select the correct statement regarding the range and mean from the provided options.
