The standard deviation for a set of data is 7.5. The mean is 235. What is the margin of error?
blondinia [14]

The margin of error is 0.97849

we are given

mean=235

so,

n=235

standard deviation =7.5

so,

\sigma=7.5

we know that

ME=2*standard error

and

SE=\frac{\sigma }{\sqrt{n} }

If confidence level is 95%, then we can multiply by 1.96

so, we can multiply by 2 to get ME

now, we can use marginal error formula

ME=\frac{2\sigma }{\sqrt{n} }

now, we can plug values

and we get

ME=\frac{2\times 7.5 }{\sqrt{235} }

ME=0.97849

the monthly budget for the front of the house is $18,000. you spent 9% of the budget on fresh flowers. How much did you spend on
Kipish [7]

To find how much was spent on fresh flowers, we just multiply 9% to the monthly budget, which is $18,000.

To multiply a percent to a number, we must first turn the percent into a decimal. Just divide the percent by 100 to get the decimal form. 9% is 0.09.

0.09 \times 18000 = 1620

$1620 was spent on fresh flowers (that's quite a lot of money!)
