Do the data provide sufficient evidence to support the claim that the mean level of the chemical 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 population standard deviation of levels of the chemical in all such tomatoes is 0.21 ppm. Seleccione una: A. Ho: µ = 0.4 ppm %3D H1: µ > 0.4 ppm Test statistic: z = 0.95 P-value: 0.1711 Do not reject Ho; At the 5% significance level, the data do not provide sufficient evidence to support the claim that the mean level of the chemical in tomatoes from this producer is greater than the recommended level of 0.4 ppm.

Question
Test the given claim. Use the P-value method or the traditional method as indicated.
Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s) or P-
value, conclusion about the null hypothesis, and 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
Do the data provide sufficient evidence to support the claim that the mean level of the chemical 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 population
standard deviation of levels of the chemical in all such tomatoes is 0.21 ppm.
Seleccione una:
Α. Ho: μ = 0.4 ppm
H;: µ > 0.4 ppm
Test statistic: z = 0.95
P-value: 0.1711
Do not reject Ho; At the 5% significance level, the data do not provide sufficient evidence to
support the claim that the mean level of the chemical in tomatoes from this producer is
greater than the recommended level of 0.4 ppm.
