Question

you try to start your car, but it does not start. which of these is a testable hypothesis?

my car will not start.

my car’s battery is dead.

my car is too old to function properly.

if i recharge the battery, then my car will start.

Explanation:

A testable hypothesis makes a specific, falsifiable prediction that can be directly tested through an action.

• "My car will not start" is an observation, not a hypothesis.
• "My car's battery is dead" is a claim but not a predictive testable statement on its own.
• "My car is too old to function properly" is vague and not directly testable with a clear action.
• "If I recharge the battery, then my car will start" proposes a specific action (recharging the battery) and a measurable outcome (car starting), which can be directly tested.

Answer:

D. If I recharge the battery, then my car will start.
