Step-by-step explanation:
Given : According to a 2009 Reader's Digest article, people throw away approximately 10% of what they buy at the grocery store.
i.e. the proportion of the people throw away what they buy at the grocery store![p=0.10](/tpl/images/0229/6548/ad196.png)
Test statistic for population proportion : -
For![\hat{p}=0.02](/tpl/images/0229/6548/f5d95.png)
Now by using the standard normal distribution table , the probability that the sample proportion exceeds 0.02 will be :
Hence, the probability that the sample proportion exceeds 0.02 =0.9962
