Answer #1

Ideally the sample result should be equal to the population value . However some difference is generally there due to sampling fluctuation. If the difference is small then the sample result is said to occur by chance alone and the result is considered to be insignificant.

If the difference is large then the sample result is said to be not occurred by chance alone and in that case the result is considered to be significant.

Hence,

When a sample result can not easily occur by chance alone ,the result is considered significant.

Chelsea Vowel explores the notion of Indigenous behaviours being considered transgressive when moved into a non-Indigenous (settler-defined) space.

Cultural expressions that cannot be so easily commodified can be seen as threatening, transgressive, or simply not Canadian” (68). Write an essay that explores this idea. What does she mean by “commodified” and by the term “allowably Indigenous”...

Probability tells us the chance or likelihood that a particular event will occur. Whether or not we realize it, every day we use probability to make decisions. For instance, when deciding whether to take an umbrella, we check the weather forecast to see the probability that it will rain. In this instance, probability tells us the likelihood that it will rain; however, the decision about taking an umbrella is based on an individual’s willingness to risk getting rained on. Some...
