Question

The weight of four-ounce bags of cashews packaged in a cashew plant follows normal distribution with a standard deviation of 0.03 ounce. suppose a random sample of 9 bags is to be taken from production and the mean weight of the sample is computed. the mean of this sample will likely be _____________ the population mean.

Answer 1

Since the sample size is too small (n = 9, which is less than 10) we cannot use the normal model to describe the entire population.
Therefore, we expect the sample mean to be different from the population mean.
