Answer: 1. c. There are no differences in the mean completion times among the scents compared

2. Scent; Completion Time

Explanation:

The Null Hypothesis of a research is that hypothesis which you aim to disprove because it holds that no significant relationship between the variables being researched exists.

In this scenario you are studying whether scent affects spatial reasoning abilities.

The Null Hypothesis will.be that which states that there is no relationship between scent and spartial reasoning therefore there will be no differences in the mean completion times among the scents compared.

The factor of interest is the variable that is being changed to examine a difference making it the SCENT in this scenario.

The dependent variable changes due to the Factor of Interest so it is the COMPLETION TIME.

Orlov [11]

Social Security is a program and agency that provides benefits. Angelo's father can apply for the benefits for retirement to receive an income every month after he retires.

In the United States, the Social Security Agency provides benefits to citizens, these benefits are indirectly paid by citizens through taxes. This includes:

  • Survivor benefits.
  • Benefits for retirement.
  • Benefits for disability.

When Angelo's father refers to Social Security, he is likely referring to the benefits for retirement the Social Security Agency provides. This is a great benefit because Angelo and his family will receive money every month that will replace his wage as a worker.

This means he can use this benefit to pay for basic expenses such as housing, food, education, etc. without being an active worker.
