Among randomly selected customers at a specific restaurant location, 230 ordered bowls, 180 ordered burritos, 53 ordered tacos, and 37 ordered salads. Are the national percentages a good fit to ordering habits observed at this location? Use all seven steps of hypothesis testing with α = 0.01. Show hand calculations of the test statistic and calculator syntax to obtain the P-value.
