Calculate the z-scores corresponding to both 12.1 and 12.76, and find the Standard Normal Probabilities for each, using a calculator or the Standard Normal Probabilities Table. Explain how you would use those values to determine the probability a bag chosen at random will contain between 12.1 and 12.76 oz.

[On Table II, find the z-score that corresponds to a value of 0.025 and then use the z-score formula. On the calculator use the command invNorm(area, mean, standard deviation), where the area is the area under the normal distribution to the left of the “cutoff” value.]

In short look up (1-0.93)/2=.035 in the middle of the table and z is the absolute value of the z-score. D. The sampling distribution of is the distribution of values taken by in . all possible samples of the same size from the same population. B. Because we infer conclusions about the population from data on selected . Individuals (all sample ...

In general, the probability that x gets a value c, P(x=c), is defined as . the sum of all corresponding outcomes in S (i.e., the sample space) that are assigned to the value . x. Ex. x = # of heads in tossing 2 fair coins. 3. There are 3 ways to display a probability distribution for a discrete r.v.: through a density plot. through a table ...

The z-value is obtained by plotting the logarithms of at least 2 D-values against temperature or by the formula: Z = (T2-T1)/(logD1-logD2) Where T = temperature and D = D-value. The z-value of an organism is the temperature, in degrees Fahrenheit, that is required for the thermal destruction curve to …
