the wait times at a restaurant are shown. select the three statements that describe the data set. restaurant…

Explanation:

Step1: Count data - set values

Count the number of dots in the dot - plot. There are 1 + 5+ 1+ 2+ 3 = 12 values. Since 12 is an even number, the data set has an even number of values.

Step2: Calculate the median position

For a data set with (n) values (where (n = 12)), the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered values. (\frac{n}{2}=\frac{12}{2}=6) and (\frac{n}{2}+1 = 7).

Step3: Order the data and find median

Ordering the data values from the dot - plot: 15 (1 time), 16 (5 times), 17 (1 time), 18 (2 times), 19 (3 times). The 6th and 7th ordered values are both 16. The median is (\frac{16 + 16}{2}=16), so the median is one of the values in the data set.

Answer:

The data set has an even number of values. The median is one of the values in the data set.
