Answer:
The most appropriate type of data to make of the sampled data is dot plot.
Step-by-step explanation:
This is because the data to be collected & analyzed is quantitative in nature and a dot plot would help to give all the measures of statistics of the data as required in the question.
These statistics required in the question, that is, the center, the shape, spread and outliers of the data won't be possible in scatter plot (because it is a single realization of the data set), the bar chart (because this represents categorical data against their numbers & the data here need not be categorized) and the pie chart (plots the percentage area covered by variable - not suitable for this data type).
Thus, the best and most appropriate chart would be to plot a dot plot.
Hope this Helps!!!
