  • Define
  • Measure
  • Improve
  • Analyze
Answer: Analyze
Q7 | The South African government is concerned about the high incidence of HIV/AIDS in South Africa. They wish to estimate the true number of people in South Africa who are HIV positive. A random sample of 5000 people was tested and 1980 of them were HIV positive. What is the statistic?
  • The 5000 people sampled
  • All the people in South Africa
  • Impossible to calculate from the given information
  • The 1980 people sampled who were HIV positive
Answer: The 1980 people sampled who were HIV positive
Q8 | In case someone is interested in process standard deviation, he should construct the______________ chart.
  • X bar
  • R chart
  • S chart
  • None of these
Answer: S chart
Q9 | The value of Var (3 - 4X) is:
  • 5120 / 9
  • 1280 / 81
  • 5120 / 81
  • 1280 / 9
Answer: 5120 / 81
Q10 | Suppose box A contains 4 red and 5 blue coins and box B contains 6 red and 3 blue coins. A coin is chosen at random from the box A and placed in box B. Finally, a coin is chosen atrandom from among those now in box B. What is the probability a blue coin was transferred from box A to box B given that the coin chosen from box B is red?
  • 15/29
  • 14/29
  • 1/2
  • 7/10
Answer: 15/29
Q11 | A multiple-choice test has 30 questions. There are 4 choices for each question. A student who has not studied for the test decides to answer all the questions randomly by guessing the answer to each question. Which of the following probability distributions can be used to calculate the student's chance of getting at least 20 questions right?
  • Exponential
  • Normal
  • Poisson
  • Binomial
Answer: Binomial
Q12 | Which of the following is NOT true about the standard error of a statistic?
  • The standard error measures, roughly, the average difference between the statistic and the population parameter.
  • The standard error is the estimated standard deviation of the sampling distribution for the statistic.
  • The standard error can never be a negative number.
  • The standard error increases as the sample size(s) increases.
Answer: The standard error increases as the sample size(s) increases.
Q13 | A two-tailed test is one where:
  • results in only one direction can lead to rejection of the null hypothesis
  • negative sample means lead to rejection of the null hypothesis
  • results in either of two directions can lead to rejection of the null hypothesis
  • no results lead to the rejection of the null hypothesis
Answer: results in either of two directions can lead to rejection of the null hypothesis
Q14 | The chi-square test can be too sensitive if the sample is:

Answer: a positive number close to 1.00

Answer: within groups
Q17 | In one-way ANOVA, which of the following is used within the F-ratio as a measurement ofthe variance of individual observations?
