Test the claim that for the population of college students, the mean weight equals to 132 lb. Sample data are summarized as n=101, x¯¯¯x¯x¯¯¯x¯=137 lb, s=14.2 lb. Use a significant level of 0.10.
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?
