A survey of 1071 adults in a country, asking "As you may know, as part of its effort to investigate terrorism, a federal government agency obtained records from larger telephone and
Internet companies in order to compile telephone call logs and Internet communications. Based on what you have heard or read about the program, would you say that you approve
or disapprove of this government program?" Of those surveyed, 568 said they disapprove.
a. Determine and interpret the sample proportion.
b. At the 1% significance level, do the data provide sufficient evidence to conclude that a majority (more than 50%) of adults in the country disapprove of this government surveillance
program?
