Let a silver rod 20 cm longinitially has a uniform temperature of 100°𝐶throughout.Suppose that at 𝑡=0the ends of the bar are plunged into an ice bath at 0°𝐶and thereafter maintained at this temperature, but that no heat is allowed to escape through the lateral surface. The thermal diffusivityof silver is𝛼2=1.71𝑐𝑚2/𝑠𝑒𝑐a) State the boundary value problem and use the method for separation of variables to find the expression for the temperature at any point 𝑥in the rod at any time𝑡. Explain why the method for separation of variables can beapplied.

b) Determine the temperature at the center of the rod at time 𝑡=30sec (Use the firstterm ofthe solution)

c) Find/estimate the time that will elapse before the center of the rodcools to a temperature of 5°𝐶. (Use the firstterm ofthe solution)

What does “statistical significance” mean in relation to this question

/in /by

A continuing debate in public health circles concerns the dangers of being exposed to dioxin, an environmental contaminant. A German study published in the October 19, 1991, issue of The Lancet, a British medical journal, considered records of workers at an herbicide manufacturing plant that made use of dioxin. A control group consisted of workers at a nearby gas supply company who had similar medical profiles.

The following data relating to the number of workers who had died from cancer were obtained.

Control group          Dioxin-exposed group

Sample size                           1583                      1242

Number dying from cancer   113                          123

Discuss the question: Is there a statistically significant difference in the rate of cancer deaths in the two groups?

Include the following points in your discussion:

  1. What does “statistical significance” mean in relation to this question
  2. Why isn’t it enough to say that “since there are more cancer deaths in the Dioxin group with a smaller sample, it is clear that exposure to Dioxin causes a higher probability of dying from cancer”
  3. Does the word “rate” indicate sample means or sample proportions?
  4. Construct a hypothesis test for this question
  5. Perform the hypothesis test analysis for a significance level of 1%
  6. What is the p-value for this test?
