Identify the p valueReject or fail to reject and it is sufficient or not sufficient evidence to conclude that the mean lead concentration fall all such medicine is less than, greater than, not equal to 14ug

Listed below are the lead concentrations in ug/g measured in different traditional medicines. Use a 0.01 significance level to test the claim that the mean lead concentration for all such medicines is less than 16 ug/g. Assume that the sample is a simple random sample. 11.5 22 8 15.5 17.5 20.5 7 7 13 12 0 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? DA. Ho: > 16 ug/g OB. Ho : p = 16 pg/g H, : H
