Explain what a p-value represents. Explain what the significance level for a hypothesis test, a, represents.
What does the p-value represent in a test of hypothesis? The p-value represents the significance level of the hypothesis test. The p-value is the probability that the sample data occurred given that the null hypothesis is true. The p-value is the probability that the sample data occurred given that the alternative hypothesis is true. The p-value is the probability that the null hypothesis is true.

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.
9.15 Toxic Mushrooms? Cadmium, a heavy metal, is toxic to ani- mals. Mushrooms, however, are able to absorb and accumulate cad- mium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and pub- lished the results in the paper "Influence of Some Factors in Toxi- city and Accumulation of Cd from Edible Wild Macrofungi in NW Spain" (Journal of Environmental Science and Health, Vol. B33(4), pp. 439-455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government's recommended limit.
