If an association between an exposure and an associationis differs significantly in strata of a third variable there isan interaction between an exposure and that thirdvariable.O TrueO False Which explanation should be considered wheninterpreting an observed association in an epidemiologicalstudy after consideration and control of selection andinformation biases? (choose one best answer)O The observed association may be due to chance alone.O The observed association may be due to problems in studydesign which result in selection bias and/or information biasand thus the association is spurious.O The observed association may be due to a third factor that isclosely related to both the exposure and the disease in thestudy population.O The observed association may be causal (exposure causesdisease).

In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams. You put the sample into 15.6 mL ofwater and the total volume rises to 22.4 ml. What metal do you have?4b. You weigh your sample and determine it weighs 56.3 grams.
