You recorded the weekly distance you bicycled in miles and computed the standard deviation to be s= 3.1 miles. your friend wants to know the standard deviation in kilometers. Do you need to redo all the calculations?
No need to redo all the calculations. we use the given standard deviation. We convert the given standard deviation miles into kilometers.
Given 1 mile ≈ 1.6 kilometers
So 3 miles = 1.6 * 3.1 = 4.96 kilometers
standard deviation = 4.96 kilometers.
Let's calculate all expenses per month
a) Mortgage $1,255 →→→→→→→→→ = $1,255 per month
b)Taxes $2,881 per year →→ $2,881/12 = $240.083 per month
c) insurance $156 →→→→→→→→→→ =$156 per month
d) HOA fees $320 per year→→→=$320/12 = $ 26.66 per month
e)utilities $475→→→→→→→→→→→→→=$475
Average monthly expenditure: a) + b) + c) + d) = $2,152.75
