Final Answer:
The survey suggests that the proportion of satisfied users with cell phone coverage may differ from the national average of 20%.
Step-by-step explanation:
The Ipsos survey, sampling 25 customers at random without replacement, aims to gauge user satisfaction with cell phone coverage across Canada.
When dealing with smaller sample sizes relative to the population, the results can vary considerably from the actual population parameters. In this scenario, the sample size of 25 may not accurately represent the entire nation's sentiments regarding cell phone coverage satisfaction.
Given that the survey was conducted randomly without replacement and assuming independence among the sampled customers, the margin of error could be significant. With only 25 individuals in the sample, the variability and uncertainty in reflecting the true population sentiment are considerable.
A proportion of 20% satisfaction nationwide acts as a reference point. However, due to the small sample size, the survey's outcome might not align precisely with this national average.
The survey results could indicate a higher or lower satisfaction rate than the national average, but with a substantial degree of uncertainty.Factors like geographic distribution, demographics, or specific carrier services among the sampled individuals might skew the results.
Therefore, while the survey implies a divergence from the national average, it's crucial to interpret the findings with caution, considering the inherent limitations of the sample size in reflecting the broader population's sentiment towards cell phone coverage satisfaction.
