The following data set shows the number of chirps in one minute from a cricket and the temperature outside (in degrees Fahrenheit):

Chirps per Minute Temperature
98 58.4
107 67.5
111 54.4
112 67.2
113 68.4
120 62.2
123 76
129 69.3
137 65.9
140 66
142 67.2
148 64.7
151 80.4
158 76.4
165 84.5

What is the rank correlation coefficient?  (Round to three decimal places.)

What is the critical rho value at a 0.01 significance?

Do we have correlation?

  • No, the rank correlation coefficient is larger (in absolute value) than the critical rho value.
  • No, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
  • Yes, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
  • Yes, the rank correlation coefficient is larger (in absolute value) than the critical rho value.

1:) The dataset shows 15 observations of the relationship between cricket chirps (measured in chirps per second) and outside ground temperature (in Fahrenheit). A. Create a scatterplot by putting chirps on the vertical axis and temperature on the horizontal axis. Be sure to properly label the scatterplot with a title, axes titles, and the proper units of the variables. B. Estimate the following relationship: ?h????=?0+?1???????????(Chirps) ̂=b_0+b_1 Temperature. C. Interpret the slope in the context of the problem. D. Interpret the...
