The weights of running shoes have an unknown distribution with mean 13 and standard deviation 3 ounces. a sample, with size n=70, is randomly drawn from the population and the values are added together. using the central limit theorem for sums, what is the mean for the sample sum distribution?

910

Step-by-step explanation:

mean for sample sums (μΣₓ)= (n)(μ)

where μ = mean = 13

n= sample size = 70

therefore

mean for sample sums = 13 x 70 = 910

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
