Answer:
Cannot be determined
Explanation:
a. The hypotheses are:
H0: μ ≥ 857.50 (null hypothesis) HA: μ < 857.50 (alternative hypothesis)
b-1. We need more information to calculate the test statistic.
b-2. We need more information to calculate the p-value.
c. To determine the conclusion, we need to compare the p-value to the level of significance (α).
If the p-value is less than α (0.05), we reject the null hypothesis (H0). If the p-value is greater than or equal to α (0.05), we fail to reject the null hypothesis (H0).
We do not have the p-value to compare with α yet, so we cannot make a conclusion.
Therefore, the answer to multiple choice 1 is H0: μ ≥ 857.50; HA: μ < 857.50, and the answer to multiple choice 2 is cannot be determined yet.
