ATP levels of 15 individuals have been measured before and after an hour of card

Question

ATP levels of 15 individuals have been measured before and after an hour of cardio exercise. What hypothesis test should be used to determine if there is a difference in ATP production before and after exercise? Zookeepers and conservationists are working together to study the activity and sleep patterns of primates. They would like to determine if there is a difference in sleeping patterns between primates in captivity vs. the wild and have measured the hours of sleep of 10 primates from the zoo and 8 from the wild. How should these data be analyzed, if the data is not normal? Tail and body lengths of 25 bearded dragons have been measured in centimeters. What analysis should be used to determine if there is a relationship between tail and body lengths in bearded dragons. Researchers are looking to see if taking exams at a certain time of day affects the outcome of exam scores. They have measured a total of 218 students of which 115 were male and 103 were female. Of the total number of students, 70 males and 68 females took the exam in the late afternoon and passed. 45 males and 35 females took the exam in the morning and passed. a) What hypothesis test should be used to analyze these data? b) Conduct the actual hypothesis test to analyze the data at 0.05.

Explanation / Answer

1. As n=15 we will need to use t test. Now as it is test for paired ATP level.

Hence we will use paired t test.
