Question

a sports magazine reports that the mean number of hot dogs sold by hot dog vendors at a certain sporting event is equal to 150. a random sample of 50 hot dog vendors was selected, and the mean number of hot dogs sold by the vendors at the sporting event was 140. for samples of size 50, which of the following is true about the sampling distribution of the sample mean number of hot dogs sold by hot dog vendors at the sporting event?

Answer 1

The sampling distribution of the sample means the number of hot dogs sold by hot dog vendors at the sporting event is approximately average, with a mean of 150 and a standard deviation of (standard deviation of the population/square root of sample size). The sample means of 140 falls within this normal distribution, and since the sample size is 50, it is likely that the sample mean is not equal to the population means.
