Let's go through each question:
**Question 1: What is the range of the data set?**
- Range is the difference between the maximum and minimum values in a data set.
- The maximum value is 48, and the minimum value is 20.
- Range = Maximum - Minimum = 48 - 20 = 28.
**Answer: 28**
**Question 2: What is the median of the data table?**
- To find the median, we need to arrange the data in ascending order.
- The data in ascending order: 20, 20, 25, 30, 35, 45, 45.
- Since there is an even number of values, the median is the average of the two middle values, which are 30 and 35.
- Median = (30 + 35) / 2 = 65 / 2 = 32.5.
**Answer: 32.5**
**Question 3: Select the data set with more than one mode.**
- Mode is the value that appears most frequently.
- The set with more than one mode is: 26, 23, 19, 25, 23.
**Answer: 26, 23, 19, 25, 23**
**Question 4: Select the data set with no mode.**
- Mode is the value that appears most frequently. If no value repeats, there is no mode.
- The set with no mode is: 38, 34, 26, 29, 40.
**Answer: 38, 34, 26, 29, 40**
**Question 5: What is the mode of the data set?**
- Mode is the value that appears most frequently.
- The mode is 23 as it appears twice, while the other values appear only once.
**Answer: 23**
**Question 6: Select the expression that shows how much more time was spent reading on Thursday than Saturday.**
- Thursday: 35 minutes, Saturday: 20 minutes.
- The expression is: Thursday time - Saturday time = 35 - 20.
**Answer: 35 - 20**
**Question 7: What is the total number of minutes spent reading?**
- Add up the time spent on each day: 30 + 25 + 45 + 35 + 20 + 20 + 45.
**Answer: 220 minutes**
