Problem 54GP

If you began walking along one of Earth’s lines of longitude and walked until you had changed latitude by 1 minute of arc (there are 60 minutes per degree), how far would you have walked (in miles)? This distance is called “nautical mile.”

Step-by-Step Solution:
Step 1 of 3

The Coefficient of Variation: C.V. = S / x(bar) X(bar)  Mean of data Examples: #1 X(bar)  54 ft S  26 ft C.V. = S / x(bar) = 26/54 = .48 or 48% #2 X(bar)  2 hours S  2.7 hours C.V. = 2.7 / 2 = 1.35 NOTICE: the units cancel when you divide the two numbers, therefore the answer does not have units!! Chebyster’s Theorem: For any set of numbers with mean x(bar) and standard deviation, S, atleast (1 – (1/ k^2) x 100%) of those numbers must fall between [x(bar) – kS] and [x(bar) + kS] ________________________________________________________________________ Quartiles: specific values that attempt to divide quantitative data into four equal parts. 1. find median 2. take median of lower half and upper half 3. then you will find the three medians, th
