A sample is selected from a population with a mean of μ = 65 and a standard deviation of σ = 15. If the sample has n = 9 scores, what are the expected value of M and the standard error of M?

answer: 1, 3 and 5 are correct

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

can you make your screen more see able?

then i might be able to .

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
