Avariable of a population has a mean of muequals78 and a standard deviation of sigmaequals32. a. identify the sampling distribution of the sample mean for samples of size 64. b. in answering part (a), what assumptions did you make about the distribution of the variable? c. can you answer part (a) if the sample size is 25 instead of 64? why or why not?

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

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:
