BACKGROUND INFO: Use the information below to answer the CANCER SURVIVAL questions that follow. Some bronchial cancer patients had the following survival times (in days) after receiving a certain treatment: 20, 37, 63, 64, 72, 81, 138, 151, 155, 166, 166, 223, 245, 246, 450, 459. (The second instance of “166” is not a mistake.) Do these numbers suggest that the average survival time, for all bronchial cancer patients who receive that treatment, is significantly different from 200 days? QUESTION I NEED TO BE ANSWERED: Report an appropriate one-sample hypothesis test and use a 10% significance level. For Step 6 of the six-step process that was taught in this class, what would be the final conclusion? A. The P-value is low so we cannot conclude that the average survival time is significantly different from 200 days. B. The P-value is not very low so our conclusion is that the average survival time is significantly different from 200 days. C. The P-value is not very low…

Penalty Shots in World Cup Soccer A study¹ of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only 41 % of the time. The article notes that this is "slightly worse than random chance." We use these data as a sample of all World Cup penalty shots ever. Test at a 5 % significance level to see whether there is evidence that the percent guessed correctly is less than 50 % . The sample size is large enough to use the normal distribution. The standard error from a randomization distribution under the null hypothesis is SE= 0.043. 1St.John, A., "Physics of a World Cup Penalty-Kick Shootout - 2010 World Cup Penalty Kicks," Popular Mechanics, June 14, 2010.
