The owner decides to test their belief. Each time Watson sees a cat, they measure the length of the cat (in cm) and count how many times Watson barks. In total, the data comprise 60 cat sightings, the first four observations of which are as follows: cat.length 32.1 64.0 42.4 46.7 summary(bark.fit) The owner runs the following code in R: barks 3 bark.fit |z|) 0.27577 -1.913 0.0558 0.00548 8.918 <2e-16 *** Signif. codes: 0 ***** 0.001 **** 0.01 **³0.05.¹0.1³ 1 (Dispersion parameter for poisson family taken to be 1) Based on this output, which of the following interpretations is correct? (You may need to use either R or a calculator to complete this question.) O We estimate that, for every 10 cm increase in cat length, the expected number of barks is multiplied by about 10.5. We estimate that, for every 1 cm increase in cat length, the expected number of barks increases by about 0.05. We estimate that, for every 10 cm increase in cat length, the expected number of barks increases by about 63%. O We estimate that, for every 1 cm increase in cat length, the odds of Watson barking is multiplied by about 1.05. A biologist wishes to see how the food consumption of lizards differs between males and females, and also between adults and juveniles. They allow 20 lizards open access to food for 24 hours, and record how much each consumes in grams.

There is no evidence of a difference in average consumption between juvenile females and adult females. O We estimate that, on average, adults consume about 10.9 grams of food more than juveniles, regardless of their sex.
