The mayor of a town read an article that claimed the national unemployment rate was 8%. They suspected that the unemployment rate was lower in their town, so they took a sample of 128 residents to test Ho p = 0.08 versus Ha: p < 0.08, where 0 а p is the proportion of residents that are unemployed. They found that 8 residents in the sample were unemployed. Using these results, they calculated a test statistic of z≈ -0.73 and a P-value of approximately 0.23. Assuming the conditions for inference were met, what is an appropriate conclusion at the a = 0.10 significance level?
