A student group measures the salinity of a water sample three times, obtaining the following results: 36.1, 35.7, and 35.8 ppt. Calculate the sample standard deviation of these measurements. Enter your result in decimal notation with an appropriate number of significant figures. Enter only the numbers, omitting the units.

Step-by-step explanation:

Standard Deviation where μ=mean, N=number of data

The results are:x= 36.1, 35.7, and 35.8

First, we determine the mean

Mean, μ= (36.1 + 35.7 + 35.8)/3=107.6/3=35.9

Next, for each x, we determine the mean deviation, x-μ

If x=36.1, |x-μ|=|35.1-35.9|=0.8 and =0.64

If x=35.7, |x-μ|=|35.7-35.9|=0.2 and =0.04

If x=35.8, |x-μ|=|35.8-35.9|=0.1 and =0.01

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
