Question

select the correct answer from each drop-down menu.

in an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. he studies two set of people-those who exercise every day for an hour and those who dont exercise at all. in this case, the statement that people who exercise for an hour may have lower cholesterol levels is choose an answer. to test this statement, the scientist would measure cholesterol levels in exercisers and non-exercisers. the cholesterol levels would be choose an answer.

Explanation:

Identificar la naturaleza de la afirmación

La afirmación "las personas que hacen ejercicio durante una hora pueden tener niveles más bajos de colesterol" es una explicación tentativa y comprobable para una observación. Por lo tanto, representa una hipótesis científica (Scientific Hypothesis).

Determinar el papel de la variable medida

Para probar esta hipótesis, el científico mide los niveles de colesterol en ambos grupos. Dado que los niveles de colesterol son el resultado o efecto que se mide y que depende de si las personas hacen ejercicio o no, los niveles de colesterol representan la variable dependiente (Experimental Variables).

Answer:

In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people—those who exercise every day for an hour and those who don't exercise at all. In this case, the statement that people who exercise for an hour may have lower cholesterol levels is <blank>a hypothesis</blank>. To test this statement, the scientist would measure cholesterol levels in exercisers and non-exercisers; the cholesterol levels would be <blank>the dependent variable</blank>.
