The plasticity of a polyethylene is affected by the concentration of a solution. When lowconcentration of the solution is used, the true mean plasticity is 55. And when high concentration isused, the mean plasticity is 62. The standard deviation of plasticity is 4 regardless of concentration ofthe solution. If two random samples of size 18 are taken, find the probability that Xhigh – Xlow 2 5.Include your solutions.O a. Probability is about 7%O b. Probability is about 98%O C.

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00degrees C. Assume 2.4% of the thermometers are rejected because they have readings that are too high and another 2.4% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. A. The cutoff values are degrees. (Use a comma to separate answers as needed.

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna). (Reference: Hummingbirds, K. Long, W. Alther.) Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and ? = 0.64 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is ? = 4.30 grams. Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.30 grams? Use ? = 0.10. Level of significance = .10 Null and alternate hypotheses. - H0: ? = 4.3 g; H1: ? < 4.3 g; left-tailed Sampling Distribution - The standard normal, since we assume that x has a normal distribution with known ?
