Petroleum pollution in oceans stimulates the growth of certain bacteria. An assessment of this growth has been madew by counting the bacteria in each of 5 randomly chosen specimens of ocean water (of a fixed size). The 5 counts obtained were as follows.

41, 62, 45, 48, 69

Find the deviation of this sample of numbers. Round your answers to at least two decimal places.

The standard deviation for given sample is 11.94    

Step-by-step explanation:

We are given the following sample of count of bacteria:

41, 62, 45, 48, 69

Formula:

where are data points, is the mean and n is the number of observations.  

Deviation from mean:

-12, 9, -8, -5, 16

Sum of squares of differences =

144 + 81 + 64 + 25 + 256 = 570

Thus, the standard deviation for given sample is 11.94

answer: a clock

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

265 words per minute

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
