Answer:YES , It would be appropriate for her to analyze her data using an independent samples t-test

Explanation:

The independent samples t-test is used to make comparisons between two independent groups so that it can be established that there is a major difference between these two groups statistically .

It can not be used to compare more than two groups. The participants of each group will stick to their original group without interfering with the other group.

If the sample data was properly gathered and when the sample mean is calculated, if the sample mean is different than the popula
juin [17]

Answer:

The answer would be sampling error.

Explanation:

Sampling error occurs when the sample taken is unrepresentative of the overall population. A study population is a group of individuals selected for research who all share a common characteristic. Ideally a sample is a random selection of people from the study population. You get a sampling error when the sample is not representative of the entire study population.  This can occur for example if your study population is anyone under the age of 2, for example, and some other characteristic is over represented in your sample, like you only selected 2 year-olds from upper class families. This is something that could make the sample mean different from the population mean.

How did Asoka incorporate the well-being of his people into activities such as trade along the Royal Road?
kiruha [24]

The correct answer to this open question is the following.

Emperor Asoka incorporated the well-being of his people into activities such as trade along the Royal Road in offering fair trade regulations that promoted commerce between the regions as a way to maintain peaceful relationships, instead of difference that would create conflicts.

Emperor Asoka inherited the ruling of the Mauryan Empire in 273 BC. He followed his grandfather's steps. He conquered, fought many battles, and imposed his will in his new territories. However, he got tired when he realized all the pain and suffering caused by the war. He converted to Buddhism and started to appreciate values such as tolerance, justice, and respect.
