Question: Question-
A medical researcher estimates that no more than 55% of adults eat breakfast every day. In a random sample of 250 adults, 56.4% say they eat breakfast every day. At \(\alpha \) = 0.01, is there enough evidence to reject the researcher’s claim?
- Write the claim mathematically and identify Ho and Ha
- Find the critical value(s) and identify the rejection region
- Find the standardized test statistic
- Decide whether to reject or fail to reject the null hypothesis
- Interpret the decision in the context of the original claim
