hoa [83]

Answer:

A. Mean = 402.5

B. Variance = 77,556.25

C. Standard Deviation = 278.49

Step-by-step explanation:

Let's calculate the mean, variance and standard deviation of the set of numbers given:

A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 = 402.5

B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 = 77,556.25

C. Standard Deviation = √Variance = √77,556.25 = 278.49
