1. An article about women in business claims that 28% of all small businesses in the United States are owned by women. Sally Parks believes that this figure is overstated. A random sample of 2,000 small businesses is selected with 546 being owned by women.

Sample Size = 400 Sample Mean = $10.68 Sample Standard Deviation = $2.70 Does the sample data provide evidence that the mean hourly wage for private sector workers for their first job is greater than $10.33 (using a = .10)? Use the hypothesis testing procedure outlined below.
