If the data from two geiger counters are combined, how will the standard deviation of the new data set compare to that of each of the indivdual geiger counters?

Step-by-step explanation:

Standard deviation is the measure of variation of a set of value. The standard deviation increases as the variation of the data increases.

For a two similar data values of Geiger counters, if new data set were compared to that of each of the individual Geiger counters then the standard deviation would decrease as the effect of increasing sample size. But in a situation where the Geiger counter data values are well distributed with varying data values and well distributed range in value, the standard deviation would increase.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
