A researcher wished to estimate the number of households with two cars. How large a sample is needed in order to be 95% confident that the sample proportion will not differ from the true proportion by more than 4%. A previous study indicates that the proportion of households with two cars is 22%
Create a flow diagram for entire process. Include flow paths for students (solid lines) and prescriptions (dashed lines).
Drug sniffing dogs must be 95% accurate. A new dog is being tested and is right in 46 of 50 trials. Find a 95% confidence interval for the proportion of times the dog will be correct.

Use population distribution to determine expected juror frequencies. Test researcher's claim at a = 0.01.
Carefully define a standard normal distribution. Why does a researcher want to go from a normal distribution to a standard normal distribution? Explain.
Suppose the horses in a large stable have a mean weight of 1464 lbs, and a standard deviation of 111. What is the probability that the mean weight of the sample horses would differ from the population mean by less than 11 lbs if 34 horses are samp..
The standard screening test for Down's syndrome is based on a combination of maternal age and the level of serum alpha fetoprotein. Using the test 80% of Down's syndrome cases can be identified while 5% of normals are detected as positives.
A researcher used stepwise regression to create regression models to predict Birth-Rate (births per1000) using five predictors:
