Answer:
The sample standard deviation is 15.3.
Step-by-step explanation:
Given data items,
84, 85, 83, 63, 61, 100, 98,
Number of data items, N = 7,
Let x represents the data item,
Mean of the data points,
Hence, sample standard deviation would be,
12/20 = 0.6, 10/25 = 0.4 = NO
12/18 =0.66, 10/15 = 0.66 = YES
5/3 = 1.6, 3/5 = 0.6 = NO
8/16 = 0.5, 3/4 =0.75 = NO
Answer is B
64 cubic inch=4 inch
To calculate the cubic inches in a easy way, we can convert all the unit to inches first, then, multiply length, width and height values together, this will give you the volume of the cube.
The answer is $64.25 or you could say its B.
Hope this helps :)
