A developer asserts that the mean number of visitors to a website is less than 800 per day. They sample 28 days and compute a sample mean of 789 visitors. The population standard deviation is 70 visitors. Is this sufficient evidence for the claim? a. State the Null and Alternative Hypotheses.
b. Compute the value of the test statistic.
c. Compute the P-value.
d. Based on the P-value, what decision should you make?

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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
