Determine which of the following observations are testable F

Determine which of the following observations are testable. For those that are testable:

Determine if the observation is qualitative or quantitative.Write a hypothesis and null hypothesis.What would be your experimental approach?What are the dependent and independent variables?What are your controls - both positive and negative?How will you collect your data?How will you present your data (charts, graphs, types)?How will you analyze your data?

1.When Sally eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she does not exercise and eats fatty foods.

2.George did not sleep at all the night following the start of daylight savings.

Solution

1.When Sally eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she does not exercise and eats fatty foods. ----> Testable hypothesis

(i). Hypothesis: Eating healthy foods helps in maintaining the blood pressure within the normal limits, while ingesting the fatty foods would result in raised blood pressure.

(ii). Experimental approach:

By providing the fatty foods and healthy foods to the person alternatively for a period of time and recording the blood pressure before and after the ingestion of food. Now, the difference is measured.

(iii). The independent variable: Healthy foods and fatty foods

Dependent variable: Measuring blood pressure

(iv). Positive and negative control: Blood pressure recorded before and after ingestion of meals.

(v). Data collected include the information regarding different foods and their effect on change in blood pressure. The data is observed to find the difference.

(vi). Presenting data:

Data is represented either in tables or graphs to show the effect of healthy and fatty foods on blood pressure.

2.George did not sleep at all the night following the start of daylight savings.---> Not a testable hypothesis
