Final answer:
The mean, median, and mode of the five least expensive gasoline prices are calculated. The mean is $0.67, the median is $0.75, and there is no mode.
Step-by-step explanation:
The mean is the average of a set of numbers. To find the mean, add up all the numbers and then divide by the total number of values. In this case, the five least expensive gasoline prices are $0.28, $0.74, $0.75, $0.77, and $0.82. Adding them up gives us a total of $3.36, and dividing by 5 gives us a mean of $0.67.
The median is the middle value when the numbers are arranged in ascending order. Since we have an odd number of values (5), the median is the third value, which is $0.75.
The mode is the value that appears most frequently in the set. In this case, none of the values repeat, so there is no mode.
