Obesity in children is a major concern because it puts them at risk for several serious medical problems. Some researchers believe that a major issue related to this is that children these days spend too much time watching television and not enough time being active. Based on a sample of boys of roughly the same age and height, data were collected regarding hours of television watched per day and weight. A correlation coefficient is 0.98. Please test whether the correlation is statistically significant by answering the following questions.
