The P-value for testing H₀: μ = 100 against H_a: μ ≠ 100 is 0.001. This indicates that
a. There is strong evidence that μ = 100.
b. There is strong evidence that μ ≠ 100, since if μ were equal to 100, it would be unusual to obtain data such as those observed.
c. The probability that μ = 100 is 0.001.
d. The probability that μ = 100 is the significance level, usually taken to be 0.05.
