3. Environmental Science & Technology (1993) reported on a study of contaminated soil in The Netherlands. Seventy-two 400-grams soil specimens were sampled, dried, and analyzed for the contaminant cyanide. The cyanide concentration (in mg/kg) of each soil specimen was determined using an infrared microscopic method. The sample resulted in a mean cyanide level of 84 mg/kg. Assume o = 80 mg/kg. Test the hypothesis that the true mean cyanide level in soil in The Netherlands does not exceed 100 mg/kg. Use a significance level of 0.01.
