Randomly selected birth records were obtained, and categorized as listed in the table to the right. Use a 0.01 significance level to test the reasonable claim that births occur with equal frequency on the different days of the week. How might the apparent lower frequencies on Saturday and Sunday be explained?
Determine the null and alternative hypotheses.
Use the chi-square table to find the critical value.
Calculate the test statistic
