what would Dr. Beebrains alternative a null hypotheses be if she plans to use a chi-square test and expects optimal foraging to take place
Animals are often faced with choices or trade-offs in nature. A good example of this is an idea coined "optimal foraging theory." This theory states that foraging animals will try to maximize their en- ergy intake (a benefit, like food or territory), while losing a minimal 6.

In many species of foraging insects, like honey bees in the Apis genus, individuals are likely to choose or select the same host plant species to find nectar, which is termed "foral constancy" 7 12 18 12 Bee C 12 14 Scientists have suggested that foraging on familiar plant speciesBee E throughout a lifetime is less costly, and provides a more predictable Bee F Bee G 15 19 15 9 source of food for a bee. 16 Bee H Beel 16 7 To test the optimal foraging theory in honey bees, Dr. Beebrain set up a lab experiment with three fake flowers each of which had an 21 14 19 unlimited supply of a different quality of nectar (high calorie, low BeeJ calorie, and in between); the fake flowers were otherwise exactly the Sum 17 149 107 114 112 same. She marked 10 individual bees and allowed them to forage in the lab for two hours. She observed the foraging and recorded the number of visits each flower received from each bee (Table 10.5),Explanation / Answer
The hypothesis presented by Dr.Beebrains can be that bees or any animal select the same host plant species and stick to it irrespective of the amount of benefits or availability of better opportunities.The plant on which the bees or any animal lands is purely accidental and then the animal sticks to the same plant if it finds even some food there.
