What is the standard deviation of the following data set?
tia_tia [17]

Answer:

D. 14.32

SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}

The mean μ is 33.

The (x minus μ) squared are 361, 49, 49, 361 respectively.

So that the SD = \sqrt{\frac{820}{4}} \approx 14.31782...

Decrease 800 by 40% and give me the answer
Kobotan [32]
Since we are decreasing by 40%

The new value would be 100% - 40% = 60%  of the value

New value =  60% of 800

                   =  (60 / 100) * 800 = 480

Am giving you 480 as the answer.
