Answer:
0.268
Step-by-step explanation:
The point estimate for a population proportion obtained through a sample is simply given by the number of occurrences in the sample (134 uses of phone), divided by the sample size (500 non-fatal accidents). The proportion 'p' is:
[tex]p=\frac{134}{500}\\p=0.268[/tex]
The population proportion of non- fatal accidents that involved the use of a cell phone is 0.268.
