Question

The following problems will ask you to look at a set of data (observations/samples) and develop a null Hypothesis (H0) and Alternate Hypotheses (H1-n). How would you approach or answer the problem/question. Additionally, you will need to determine which of the variables in the model are dependant and which are independent, if applicable.

Problem 1. After reviewing the following data regarding how many medications are taken by people of various ages, develop Null and Alternate Hypotheses to describe the data.

Problem 2. You enter a remote region of the planet and you collect genetic data regarding 2 different populations of the same species. Develop null and alternate hypotheses. What might this tell you about the populations?

Problem 3. You enter a remote region of the planet and you collect genetic data regarding 2 different species. Develop null and alternate hypotheses. What might this tell you about the species?

Problem 4. After sampling a population of organism and their reproduction, the following pattern emerges. Develop Hypotheses.

Problem 5. A drug manufacturer is testing new antibiotics. The following data describe the % death of the bacteria and the percentage of test subjects which exhibited side effects from each drug. Describe the pattern of the data. Develop Hypotheses and briefly design an experiment.

Explanation / Answer

1) the independent variable is Age and the dependent variable is amount of medication.

Alternate Hypothesis "As the age increases, the amount of medication also increases/decreases."

Null Hypothesis "The amount of medication does not depend on the age"

2) the independent variable is one population of the species and the dependent variable is other population of species

Alternate Hypothesis "The one population of the species depend on the other population of the species"

Null Hypothesis "The two populations of the the species does not depend on each other"

3) independent variable is genetic feature of one species and dependent variable is genetic feature of second species

Alternate Hypothesis "Some features of one species is related to the other"

Null Hypothesis "There is no similarities between two species"

4. independent variable is feature of the organism and dependent variable is reproduction

Alternate Hypothesis "Reproduction of organism depends upon their size"

Null Hypothesis "There is no dependence of reproduction on the organism's feature"

5. independent variable is % death of the bacteria and dependent variable is test subjects which exhibit side effect

Alternate Hypothesis " side -effect depend on the % death of bacteria

Null Hypothesis "there is no relation in side effect with death of bacteria"
