0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
Your Answer should be True
The question is asking to find the variance for the said samples in the problem ans use the sample data to determine each variance, and base on my further computation and further calculation, I would say that the answer would be the following:
#1. 3.3 -> 1 and 3 -> 2/9
#2. 1-> 0->3/9
#3. 6.3 - > 8 and 3-> 2/9
#4 49-> 1 and 8-> 2/9
5/8 trust me because when you divide 5 by 8 you get a number that is equal to 5/8
