seven food trucks are competing to see how many customers visit their trucks per day in a busy part of the city. The average number of customers that visit each food truck per day in 41. the sum is found to be 358. calculate the variance to this data

To calculate the variance, we have to find the squared differences between each data point and the mean, sum those squared differences, and then divide by the number of data points. Calculate squared differences between each food truck's daily customers and the mean: Food truck 1: (41 - 41)^2 = 0 Food truck 2: (41 - 41)^2 = 0 Food truck 3: (41 - 41)^2 = 0 Food truck 4: (41 - 41)^2 = 0 Food truck 5: (41 - 41)^2 = 0 Food truck 6: (41 - 41)^2 = 0 Food truck 7: (41 - 41)^2 = 0 Sum of squared differences = 0 + 0 + 0 + 0 + 0 + 0 + 0 = 0 Variance = Sum of squared differences / (Number of food trucks) = 0 / 7 = 0 Variance is 0
