Explanation:
Detailed explanation-1: -The z-test is also a hypothesis test in which the z-statistic follows a normal distribution. The z-test is best used for greater-than-30 samples because, under the central limit theorem, as the number of samples gets larger, the samples are considered to be approximately normally distributed.
Detailed explanation-2: -A z-test is used if the population variance is known, or if the sample size is larger than 30, for an unknown population variance.
