How to predict the number of adults whose main source is newspapers or radio
From the question, we have the following parameters that can be used in our computation:
The table of values
Where,
Total adults in the sample = 56 + 86 + 128 + 20 + 49
Total adults in the sample = 339
The proportion of adults in the sample whose main source of news is newspapers or the radio is
Proportion = (56 + 20) / 339 = 0.224
This means that
Estimate = 0.224 * 44000
Estimate = 9856
Hence, there are an estimated 9856 adults whose main source of news is newspapers or the radio.
