Assuming that you have 50 subjects that you want to randomly assign to two different groups of 25, explain how you would use a random number table to do it.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
