Assume that 12 jurors are randomly selected from a population in which 80% of the people are Mexican-Americans.


Problem: Assume that 12 jurors are randomly selected from a population in which 80% of the people are Mexican-Americans. Refer to Table 5-1 (attached), find the indicated probability.

  1. Using the probability values in Table 5-1, find the probability value that should be used for determining whether the result of 11 Mexican-Americans among 12 jurors is usually high.
  2. Does the selection of 11 Mexican-American jurors suggest that the selection process favors Mexican-Americans? Why or why not?

Problem: Assume that a procedure yields a binomial distribution with a trial repeated n times. Use table A-1 (attached) to find the probability of x successes given the probability p of success on a given trial.

n=4,x=3,p=0.30

Problem: Standard Normal Distribution. Assume that the readings on the thermometers are normally distributed with a mean of O and a standard deviation of 1.00C. A thermometer is randomly selected and tested. In each case, draw a sketch, and find the probability of each reading (the given values are in Celsius degrees).

Between -3.90 and 1.50


Question #2 : Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test). (hint; Draw a graph in each case.

Find the IQ score separating the top 85% from the others.

Question #3 : Assume that women's heights are normally distributed with a mean given by µ=63.6 in. and a standard deviation given by ơ =2.5in. (based on data from the National Health Service.

If 1 woman is randomly selected, find the probability that her height is 63in.
