Identify the null and alternative hypotheses. Upper H 0: mu equals 31 Upper H 1: mu less than 31 (Type integers or decimals. Do not round.) Part 2 Identify the test statistic. negative 1.18 (Round to two decimal places as needed.) Part 3 Identify the P-value. 0.121 (Round to three decimal places as needed.)
