To find the p-value, we need to look up the area under the standard normal curve for the given z statistic. Using a standard normal distribution table or calculator, we can find that the area to the right of 1.82 is 0.0344. Since this is a two-tailed test, we need to double this area to get the total area in both tails: 0.0344 x 2 = 0.0688. Therefore, the p-value is 0.0688, which corresponds to choice B.
