city's environmental engineers are studying the amount of lead in drinking water. able amount being 34 parts per million. Analyses of drinking water samples for 75 a neighborhood of the city gave the following information on lead levels (in parts per million): ze: 75 .9 Deviation: 6 onmental engineers set up the null and alternative hypotheses as follows: 4 34 that the p-value = 0.099 and use an a=0.01 level of significance. Do the environmental engineers have evidence to say the levels of lead in the water are significantly higher than the standard? O Since the p-value < a. there is insufficient evidence that the levels of lead are significantly higher than the standard.

Question
Suppose a city's environmental engineers are studying the amount of lead in drinking water. An acceptable amount being 34 parts per million. Analyses of drinking water samples for 75 homes in a neighborhood of the city gave the following information on lead levels (in parts per million): Sample Size: 75 Mean: 34.9 Standard Deviation: 6 The environmental engineers set up the null and alternative hypotheses as follows: H₁: μ = 34 Ha: μ> 34 They find that the p-value = 0.099 and use an a=0.01 level of significance. Do the environmental engineers have enough evidence to say the levels of lead in the water are significantly higher than the standard? A. O Since the p-value < a. there is insufficient evidence that the levels of lead are significantly higher than the standard. B. O Since the p-value < a, there is sufficient evidence that the levels of lead are significantly higher than the standard. C. O Since the p-value > a, there is insufficient evidence that the levels of lead are significantly higher than the standard. D. O Since the p-value > a, there is sufficient evidence that the levels of lead are significantly higher than the standard.
