Anull hypothesis can only be rejected at the 5% significance level if and only if: a. a 95% confidence interval does not include the hypothesized value of the parameter b. a 95% confidence interval includes the hypothesized value of the parameter c. the null hypothesis is biased d. the null hypotheses includes sampling error

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
