What is the null and alternative hypothesis (statement) of the following: A 1985 study was performed focusing on the protein concentration of duodenal secretions from patients with cystic fibrosis. Table 12.3 provides data relating protein concentration to pancreatic function as measured by trypsin secretion. Which of the group is significant? Geographic distribution of COVID-19 cases in different countries. Which is significant among the countries? You might want to measure the resting heart rate of subjects one month before they start a training program, during the middle of the training program, and one month after the training program to see if there is a significant difference in mean resting heart rate across these three-time points. A researcher has randomly selected a sample of 8 adults to participate in a memory study. Each adult is administered treatment and then given a memory test. The memory test scores are standardized for comparison across the drug. A higher score indicates a better memory score. Find if significant differences exist between drug types and their effect on memory.
