the data in the dot plot are choose... and have a median of choose... hours.
based on the shape of the data, the mean time will be choose... the median time. therefore,
alexis is not correct

Explanation:

Step1: Count data points

Count all the dots in the dot - plot. There are 30 data points.

Step2: Find median position

Since \(n = 30\) (an even number), the median position is \(\frac{n}{2}=15\) and \(\frac{n}{2}+ 1 = 16\).

Step3: Determine median value

Arrange the data in ascending order (already done in the dot - plot). The 15th and 16th ordered data values are both 7. So the median is 7.

Step4: Analyze data shape and mean - median relationship

The data is symmetric. In a symmetric distribution, the mean is equal to the median.

Answer:

The data in the dot plot are symmetric and have a median of 7 hours. Based on the shape of the data, the mean time will be equal to the median time.
