The population mean is the mean of the given distribution set. To find the population mean for the data in this table, use the population mean formula: `μ = (ΣX)/N`
First, add all the scores of the 10 students: `ΣX = 790`. Then, apply the formula: `μ = (ΣX)/N = (790)/(10) = 79`. The population mean is 79.
