H Homework ' Unanswered The information in the table is from an experiment where the calling rate of tree frogs was measured as function of the ambient air temperature. The q uestion of interest was whether frog calling rate increases with increasing temperature? The data consist of 9 calling rates {measured as number of calls per 30 seconds} collected at 9 different temperatures {measured in degrees Celsius]. What is value for the intercept?What is lower boundary for the 95% confidence interval of the slope?What is degrees of freedom for the regression?Question 22: Perform a hypothesis test to determine whether the slope of the regression differs from zero. What is your conclusion? Select an answer and submit. For keyboard navigation, use the upj'down arrow keys to select an answer. a Reject the null hypothesis. The slope is not equal to zero because Fcalculated =19.287 and pyalue =0.0D4 b Fail to reject the null hypothesis. The slope does not differ from zero because Fcalculated =3.490 and pyalue =0.762 c Reject the null hypothesis. The slope is not equal to zero because Fcalculated =48.038 and pyalue =0.0DD2 d Fail to reject the null hypothesis. The slope does not differ from zero because Fcalculated =6.509 and pyalue =0.288 Fill in the Blanks A B 20 20- 15 15 calling rate calling rate 10 10 5 5 8 12 4 8 12 ambient air temperature ambient air temperature Type your answers in all of the blanks and submit Question 23: The coefficient of determination for the frog regression equals |Type your answer here (enter a numerical value).
