Pass or Fail A manutacturer is woried that their product may not be consistently good enough to pass quality control inspections. They are going to take some random samples of their product and have a quality control expert examine the items to determina if they pass or fail. To move forward with production, they need to have 80% of the items pass the inspaction. The product bag han 20 slips of paper with 14 of them markod "Pass" and 6 marked "Fail." From the results of the first trial, estimato the proportion of the slips in the bag that aro marked Pass. Complete the table.

A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or a placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below. Preterm Delivery Experimental Drug Standard Drug Placebo Yes 17 23 35 No 83 77 65 Is there a statistically significant difference in the proportions of women delivering preterm among the three treatment groups? Run the test at a 5% le significance.
This problem is designed to help you see the effect of outliers can have on an ANOVA test.Students enrolled in developmental mathematics classes at a community college are encouraged to go to the Math Tutoring Center (MTC) for help with their homework. Some students schedule their time so that they go once or twice a week to focus on all of their math homework at once. Some students even start forming study groups and meet at the MTC to work together. The staff that run the MTC want to know if some classes are using their services more than others. They collect data from 5 classes and 17 students per class that attend the session at least once in the term. The dependent variable is the number of days a student visits the MTC during one academic term (about 12-13 weeks).

The “Wild Safari” theme park allows visitors to drive their own vehicles across more than 400 acres of land that house thousands of freely roaming animals. At the entrance, a sign warns tourists that there is a 65% chance that a car will take some damage by an animal during the visit. We will use blue poker chips to represent cars that take some damage and yellow poker chips to represent cars that do not take some damage. We will use a total of 100 poker chips to simulate the null hypothesis model. How many of the 100 poker chips should be blue? A. 20 Poker Chips B. 50 Poker Chips C. 65 Poker Chips
If there is a significant interaction in a factorial design, why do researchers typically ignore (or minimize the importance of) the main effects?
The Wall Street Journal asked Concur Technologies, Inc., an expense management company, to examine data from 8.3 million expense reports to provide insights regarding business travel expenses. Their analysis of the data showed that New York was the most expensive city. The following table shows the average daily hotel room rate (X) and the average amount spent on entertainment (Y) for a random sample of 9 of the 25 most-visited U.S. cities. These data lead to the estimated regression equation y = 17.49 + 1.0334x. For these data SSE = 1541.4. Use Table 1 of Appendix B. a. Predict the amount spent on entertainment for a particular city that has a daily room rate of $89 (to 2 decimals). b. Develop a 95% confidence interval for the mean amount spent on entertainment for all cities that have a daily room rate of $89 (to 2 decimals). c. The average room rate in Chicago is $128. Develop a 95% prediction interval for the amount spent on entertainment in Chicago (to 2 decimals).
