In August 1976, Tuberculosis was diagnosed in a high school student (INDEX CASE) in Corinth Mississippi. Subsequent laboratory studies revealed that the student's disease was caught by drug resistant tubercule bacilli. An epidemiologic investigation was conducted at the high school.
The following table gives the rates of positive tuberculin reaction, determined for various groups of students according to degree of exposure to the index case.
Exposure level
Number tested
Number positive
High
129
63
Low
325
36
Calculate the 95% confidence interval for the rate of positive tuberculin reaction separately for each of the two subpopulation, those with high exposure and those with low exposure.
Find out the finite population correction (FPC).With a population size of 1,000 and a planned sample size of 200, what is the finite population correction.
Create a scatterlpot of P_RFM and P_HELM. If drawing plot by hand, use graph paper to make sure accuracy. Be sure you label axes. After you have created the scatterplot, consider its form and direction. Recognize outliers, if any.
Construct the following confidence intervals for your data set:
If statistically significant, do you think the difference is large enough to be important?
They find that these 100 people lost an average of 38 hours with a standard deviation of 9.5 hours. What is the P-value for this significance test?
Assume you choose 20 houses at random. On average, how many houses of twenty would you expect to have DVD? Determine standard deviation of number of houses with DVD?
Determine the probability of choosing at random license plate which ends in the even number?
Describe the sampling distribution model of this mean.
At the 5% significance level, if the sample proportion is .45, and the standard error of the sample proportion is .035, the appropriate conclusion would be:
At α = .05, is there a difference in variances? Illustrate all steps clearly, including illustration of the decision rule.
What is the relationship between the variance and the standard deviation?
What is the null hypothesis? Use α =0.05. Compute critical value. Use α =0.05.
