No, it is not safe to assume that the sampling distribution of the sample means is about normal given the sample size.

  • Based on the information provided, it was reported that a journalist chose a random sample of 15 summer weddings that were hosted in the state in order to determine the average cost of flowers for summer weddings in a particular region.
  • Note that the Z test usually includes more than 30 samples. 15 samples were used in this instance.
  • Because of this, it is not possible to assume the sampling distribution from the sample size.
