Explanation / Answer

(a) For game console replacement rate = 10.4%

(B)

There are 250 million individuals who own a cell phone

So, we have to find that the number of eople are expexted to replace their phone within the next 12 months

There are 14.9% of phone owners are willing to  replace their phone within the next 12 months as per bar chart.

so Number of such people = 250 million * 14.9/100 = 37.25 million

(c) Descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables. Inferential statistics makes inferences and predictions about a population based on a sample of data taken from the population in question.

Here we are being provided Descriptive statistics becuse the surveysampled enough adults in the country to be certain that it can be applied to population. Option B is correct.
