Summary Introduction
Introduction:
The scientific hypothesis can be defined as an idea or explanation or a proposed explanation which is then tested through the scientific study and experimentation. It is based on some observation. It is usually more than a wild guess but less than a well-established theory.

a) Does the data support your hypothesis?
b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.
Which of the following animals may have been the second pet domesticated by humans, in Egypt or in Turkey (about 10,000 BCE), and probably helped to keep rodents away from cereal crops like wheat?
the domesticated dog (Canis familiaris)
the gray wolf (Canis lupus)
the domesticated cat (Felis catus)
the coyote (Canis latrans)
the Norwegian rat (Rattus norvegicus)
Bayesian updating can be a useful tool for thinking about the development of behavior. Imagine the following scenario with respect to an animal’s knowledge of the average density of food in patches in their environment. Which of the following is the most accurate interpretation of this Bayesian view of this animal?
Their environment is much richer in food resources than expected
Their confidence in their assessment of the state of the environment is greater after they go out and sample the world
Their environment is less rich than expected – perhaps there is a drought that has caused a crash in food availability relative to historical conditions
All of the above

The data includes numbers from both before and after a fungus harmed the health of the long- horned grasshoppers. Use the information below to answer the question. Organisms such as dead-leaf moths and peacock katydids depend on dead leaves on the ground floor of the Amazon for camouflage.

- Figure 1.15 Example of error bars in a graph. This graph was adapted from the peacock butterfly research described in Section 1.5. The researchers recorded the number of times each butterfly flicked its wings in response to an attack by a bird. The squares represent average frequency of wing flicking for each sample set of butterflies. The error bars that extend above and below the dots indicate the range of valuesthe sampling error. Figure It Out: What was the fastest rate at which a butterfly with no spots or sound flicked its wings?arrow_forwardIn your own understanding, answer the following questions: 1. Are leaders born or can they be trained?2. Leaders are made, not born. Explainarrow_forwardYou are designing an experiment to test the following hypothesis: Temperature affects the ability of students to think clearly, and, therefore, students in a hotter room will have lower exam scores than students in a cooler room. For your experiment, list the following Sample size Independent variable Dependent variable Control group Experimental group Standardized variables How will you ensure that you have a random sample?arrow_forward
- An adequate sample size controls for chance events and individual variationsin response and thus enables us to place more confidence in the outcome. For example, would you rather trust your health to a drug that was tested on 5 people or one tested on 5,000? Why?arrow_forwardAnswer the following questions using this information: Bowhead whales can live up to 150 years, reproducing first when they reach 25 years of age, which is when they leave their mother. The survival curve for this whale species is shown below. Indicate which answer is correct about this whale. % alive age in years 150 O They have a type 1 survival curve and show little parental care of offspring. O They have a type 2 survival curve and show strong parental care of offspring. They have a type 1 survival curve and show strong parental care of offspring O They have a type 3 survival curve and little parental care of offspring.arrow_forwardBody weight and length were measured on six mosquito fish; these measurements are given in the following table.

They separate their guppies into 6 groups, each containing 3 guppies. All groups will undergo one control trial and one experimental trial. The researchers then analyzed the results. What type of t-test did they use and what is the n of this experiment? Group of answer choices paired t-test, n = 3 unpaired t-test, n = 3 paired t-test, n = 6 unpaired t-test, n = 6 paired t-test, n = 18 unpaired t-test, n = 18arrow_forward
