Cadmium, a heavy metal, is toxic to animals. mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. the czech and slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 ppm. below are cadmium levels for a random sample of the edible mushroom boletus pinicoloa.0.24 0.92 0.59 0.19 0.62 0.330.16 0.25 0.77 0.59 1.33 0.32a) perform a hypothesis test at the 5% significance level to determine if the meancadmium level in the population of boletus pinicoloa mushrooms is greater than thegovernmentâs recommended limit of 0.5 ppm. suppose that the standard deviation ofthis populationâs cadmium levels is o( = 0.37 ppm. note that the sum of the data is 6.31 ppm. for this problem, be sure to: state your hypotheses, compute your test statistic, give the critical value.(b) find the p-value for the test.
