A new process in manufacturing fertilizers was designed to produce a mean of 880 tons per day. to evaluate the new process, the plant manager gathers the daily ton output. the process in 50 days produced an average of 871 tons per day and standard deviation of 21 tons. at 5% level of significance, test the hypothesis that the daily yield of fertilizer using the new process is less than 880 tons. Kindly answer this statustics problem. Thank you
