The weights of adult male beagles are normally distributed, with a mean of 25 pounds and a standard deviation of 4 pounds. If 75 beagles are randomly selected, then approximately how many are expected to weigh more than 30 pounds? Hint: compute probability, then multiply it by number of beagles.

A random sample is taken from an infinite population whose distribution is skewed toward smaller values. If random sampling from the population is conducted, which of the following is TRUE about the sampling distribution of the sample mean? I. As the sample size increases, the mean of the sampling distribution will become larger than the population mean. II. The standard deviation of the sampling distribution will be larger than the standard deviation of the population. III. The sampling distribution is skewed for small samples, but becomes more normal-shaped for larger samples.
