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?

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
