A random sample of 108 customers was taken in a shopping mall. The mean number of items purchased by the customers in the sample was 3.9 with a standard deviation of 1. The median was 4.4, and the mode was 4. A graph shows that the distribution of the data is highly skewed to the left. A store manager wants to calculate the probability that a customer will purchase at least 4 items. Is the statement below true?

The probability cannot be accurately determined using the mean, standard deviation, or z-score table.
