Use either the traditional method or P-value method as Indicated. Identify the null and alternative hypotheses, test statistic (indicate if ( or z), critical value(s) (indicate type), P-value, conclusion about the null hypothesis (with reason), and state the final conclusion that addresses the original claim. The maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.4 parts per million (ppm). A consumer health group measured the level of the chemical in a random sample of tomatoes obtained from one producer. The levels, in ppm, are shown below. 0.31 0.47 0.19 0.72 0.56 0.91 0.29 0.83 0.49 0.28 0.31 0.46 0.25 0.34 0.17 0.58 0.19 0.26 0.47 0.81 Use the data to test the claim that the mean level of the chernical in tomatoes from this producer is greater than the recommended level of 0.4 ppm. Use a 0.05 significance level to test the claim that these sample levels come from a population with a mean greater than 0.4 ppm. Use the P-value method of testing hypotheses. Assume that the standard deviation of levels of the chemical in all such tomatoes is 0.21 ppm. Give all numerical answers exactly or correct to 3 decimal places (as appropriate). Note: Fill in blanks for Null and Alternative Hypothesis as follows: Symbol for variable (p or Mu), then connector (", =/, , =) followed by numerical value. Ho: HI: Note: Fill in blanks for Critical Value(s) as follows: Symbol for variable (t_alpha, z_alpha, (_alpha/2 or z_alpha/2), then the sign (+, - or +/-), then numerical value (to 3 decimal places) Critical Value(s): Test Statistic (indicate t or z) followed by numerical value (to 3 decimal places)- P-Value (to 3 decimal places): Conclusion about Null Hypothesis: Reason for Conclusion about Null Hypothesis: Final Conclusion (Fill in the appropriate words or phrases to complete sentence) There is evidence to the claim that the population mean is greater than 0.4 ppm.
