Construct and interpret a 95% confidence interval for the mean age at which a baby first crawls. (round to one decimal place as needed.)
a. the lower bound is 33.1 weeks and the upper bound is 45.4 weeks. we are 95% confident that the mean age at which a baby first crawls is within the confidence interval.
b. the lower bound is 33.11 weeks and the upper bound is 45.39 weeks. we are 95% confident that the mean age at which a baby first crawls is outside of the confidence

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
