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.

Part 1 You will be presented with several relationships and will be asked to write out the null and alternative hypotheses in the proper form. In this section you will: 1. Indicate the directionality of the relationship and what are being compared. Write the null hypothesis (remember, this is in terms of the population). 2. 3. Write the alternative hypothesis (remember, this is in terms of the samples). 1. A medical student is designing a clinical trial to test a new depression medication. The student believes the medication will reduce the severity of patient depression. 2. A researcher is running a study examining a new pilot training software using virtual reality technology. The researcher feels pilots trained using VR training program will perform differently than traditionally trained pilots during a simulated landing task. 3. A police officer believes younger drivers get ticketed more than older drivers. A researcher at a local university has decided to test the police officer's…
A poll found that 59% of a sample of 1020 teens in a certain large country go online several times a day. (Treat this sample as a simple random sample.) Complete parts a through e below. Find the margin of error for this poll if we want 90% confidence in our estimate of the percent of teens in the country who go online several times a day. Explain what the margin of error means. If instead we need to be 95% confident, will the margin of error be larger or smaller? Explain. Find that margin of error.

Please circle your answers. Thank you in advanced!
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Do a minority of Michigan residents clear snow from sidewalks before 9 am after snow has fallen?For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________
