You have set a professional goal to become the lead of your city's annual Charitable Giving Campaign. The mayor has agreed to give you that role if you can inspire your team to create enough workplace goodwill that more than 60% of employees around the city increase their level of participation in the campaign this year. A random sample of post-campaign data shows that 34 of 47 employees have upped their giving this year, and you think the new title is yours. However, the next day the mayor comes up to you and says she thinks it could have been random chance that so many employees participated in the campaign this year. Show her you deserve to head up the campaign by proving her wrong! (Use = 0.05.)
