A health professional is whether stress level before a routine practice session can be used to predict the mean stress level a major figure skating competition. The health professional selected a random sample of figure skaters and measured the stress level before a routine practice session and before a major competitionEach variable was measured as the change in the interval between heartbeats , or heart rate variability . The health professional wants to estimate the mean change in the stress level before a major competition for each unit increase in the stress level before a routine practice.

The mating call frequency of American bird-voiced tree frogs appears to be related to the outside temperature. The scatterplot below show this relationship. Summary measures are: mean of frequency = 6.01 notes per second, standard deviation of frequency = 1.78 notes per second, mean of temperature = 22.61 degrees Celsius, standard deviation of temperature = 3.35 degrees Celsius, and correlation between frequency and temperature = 0.85 Compute the slope what the slope means in this context. Compute the y-intercept and interpret what the y-intercept means in this context. Describe the relationship between Temperature and Frequency. Predict the frequency when temperature is 23 and 36 degrees. Do you see any problems with wither of the predictions?
