Þorgerður, a scientist, used a paired t-test to examine the effectiveness of a drug she is developing. She obtained a p-value =% 3D 0.005 and concluded that the drug was effective (she used a = 0.05). Suppose the drug does not actually work. Which of the following statements is correct? 1. Þorgerður should not reject the null hypothesis because the p-value is too large. 2. Type I error occurred. 3. An error of type II occurred. 4. There was no error
It has long been stated that the mean temperature of humans is 98.6°F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6°F. They measured the temperatures of 56 healthy adults 1 to 4 times daily for 3 days, obtaining 250 measurements. The sample data resulted in a sample mean of 98.3°F and a sample standard deviation of 1°F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6°F at the a = 0.01 level of significance.
