The manager of a photography studio has carried out an experiment to compare the attractiveness of four different poster-size photographs for use in the display window. During 23 business days of the previous month, she randomly selected one of the four photographs for display; the data below show the number of customers for each day that a given photograph was displayed in the window. At the 0.01 level of significance, examine whether the poster-size photos could be equally effective in attracting customers into the store. Using the appropriate statistical table, what is the most accurate statement that can be made about the p-value for the test?
