Recently, research suggested that eating eggs is again considered potentially bad for your heart health. You are part of a team that did a healthy diet information talk to 50 students randomly chosen at the University of Arizona. After a year, you surveyed the same 50 people to find out if the average number of eggs eaten was significantly less than the US average of 1.7 per week. The sample mean was 1.5 eggs/week and sample standard deviation was 0.3...

The pH factor is a measure of the acidity or alkalinity of water. A reading of 7.0 is neutral; values in excess of 7.0 indicate alkalinity; those below 7.0 imply acidity. Loren Hill states that the best chance of catching bass occurs when the pH of the water is in the range 7.5 to 7.9. Suppose you suspect that acid rain is lowering the pH of your favorite fishing spot and you wish to determine whether the pH is less...
