Answer 1

A)

Assume specialist need to check whether the appropriation of the watched information or perception is same as the populace circulation or not then scientist could utilize an integrity of fit test.

Give us a chance to see a precedent assume there is a bundle of chocolates with 6 unique hues and specialists needs to check whether the extent of the chocolates with various hues is same or not.

Analyst needs to check whether the bundle of contains every one of the 6 hues in an equivalent extent or not.

Here the chi - square test for integrity of fit is fitting since we need to check regardless of whether the populace conveyance is same as the watched dissemination of the shades of the chocolates.

B)

Assume analyst need to check whether the sexual orientation of the individual and the ideological group for which individual vote is free from one another or not,then scientist would utilize chi-square test for autonomy of 2 straight out factors.

This test is proper to utilize , on the grounds that there are 2 clear cut factors, for example, sexual orientation of the individual and ideological group and analyst needs to check whether there is any relationship exists between the two factors or not.

C)

Assume analyst need to check whether there is any huge distinction in normal treatment impact of the 4 unique kinds of medications.

At that point scientist would utilize the examination of difference or Anova for checking this case.

the variable engaged with this investigation is the impact of medication.

The Anova test is suitable to use in this situation since we need to analyze multiple gatherings for this investigation, we think about 4 gatherings of individuals or patients who are given four distinct sorts of medications for their medicine.
