Based on the given study results, compute a 95% confidence interval (CI) for the true mean difference in blood lead level scores for the females population compared to the males in the population from which the NHANES sample is taken. Is this difference in means statistically significant?

a. Yes, because the 95% CI does not include 1.

b. No, because the 95% CI includes 1.

c. Yes, because the 95% CI does not include 0.

d. No, because the 95% CI includes 0.
