Please solve all parts of the question correctly. Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. A government set a safety limit for cadmium in dry vegetables at 0.5 parts permillion (ppm). The cadmium levels in a random sample of one species of edible mushroom are in the accompanying data set. At the 5% significance level, do the data provide sufficient evidence to conclude that themean cadmium level in this species of mushroom0.34 ppm.
