A school principal claims that the number of students who are tardy to school does not vary from month to month. A survey over the school year produced the following results. Using a 0.010.01 level of significance, test a teacher’s claim that the number of tardy students does vary by the month. Tardy Students Aug. Sept. Oct. Nov. Dec. Jan. Feb. Mar. Apr.
