In 2008, 46% of business owners gave a holiday gift to their employees. A 2009 survey of business owners indicated that 35% planned to provide a holiday gift to their employees (Radio WEZV, Myrtle Beach, SC, November 11, 2009). Suppose the survey results are based on a sample of 60 business owners.
a. How many business owners in the survey planned to provide a holiday gift to their employees in 2009?
b. Suppose the business owners in the sample did as they planned. Compute the p-value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts had decreased from the 2008 level.
c. Using a .05 level of significance, would you conclude that the proportion of business owners providing gifts decreased? What is the smallest level of significance for which you could draw such a conclusion?
