74.64%. The mean sales (μ) standing at 50 hot dogs and a standard deviation (σ) of 7 hot dogs. For any given volume of hot dogs sold, X, the z-score is utilized as follows: For X = 45 hot dogs, we compute the corresponding z-score. Similarly, for X = 65 hot dogs, we obtain another z-score. A z-score of -0.7143 indicates the 23.75 percentile, while z = 2.1429 represents the 98.39 percentile. This leads to the calculated probability that the vendor sells between 45 and 65 hot dogs.

The central limit theorem indicates that as the size of a sample increases, the distribution of sample means approaches a normal distribution, irrespective of the population’s original shape. Typically, this is valid when the population size, denoted as n, is 30 or more (which means greater than 29). The population’s skewness or normality is not a factor in this scenario. Therefore, with a sufficiently large group, the mean results from sampling will equal the population mean.
