Answer #1

The confidence intervals in Options-B, C, D all contain 0 between their lower and upper limits.

If a confidence interval contains 0, that implies we do not have sufficient evidence to reject the null hypothesis

The confidence interval in Option-A does not passes through 0. Hence, the null hypothesis can be rejected.

Therefore, Option-A is the correct answer:
