A research question can be defined as a specific inquiry (question) that a research work seeks to provide an answer or response to, especially by using scientific methods such as the following:
- Documenting critical information.
According to their nature, a research question is broadly classified as follows:
1. <u>Too broad:</u> what will the economy be like in the future?
- A country's economy has many facets and as such it would be difficult to write about what it would be like in the future in one research paper.
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
- Virtual reality (VR) is a modern technology that is effectively used by medical professionals in the field of medicine to provide health care for various patients.
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
- The quantity of water in gallons that would be used in 2025 can easily be calculated by using a simple formula and as such the answer to this question can be provided in a sentence.
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?

Answer:
The answer is Option A
Explanation:
Cup of milk m = 299 mg
Cup of juice j = 261 mg
Limit of intake = 1000mg
Total amount of calcium from milk = 299 × m = 299m mg
Total amount of calcium from juice = 261 × j = 261j mg
Since it must be equal to or exceeding the daily limit u use the GREATER THAN OR EQUAL TO SIGN.
299m + 261j <u>></u> 1000
The number of six samples that could belong to the same population is equivalent to six.
Option A is the correct answer.
<h3>What is the standard deviation?</h3>
The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.
