In 2006, the Texas legislature enacted a new tax on businesses, which allowed property tax relief for homeowners. Texas has traditionally had very low business-related taxes relative to most other states. A business-related advocacy group was concerned about the impact of the new taxes on the ability of Texas to recruit new businesses. To obtain a measure of the perception of business leaders about the change in the business friendly climate in Texas, the advocacy group randomly selected 150 CEOs and asked them if this new tax would have a major influence on whether they would consider expanding their business to Texas. A total of 12 CEOs responded that the new tax would have a major impact on their decision. Estimate the true proportion of CEOs that would feel that the new tax would have a major impact on a decision to expand their business in Texas. Use a 95% confidence interval as your estimator.
