Based on what you have heard or read about the program, would you say that you approveor 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 surveillanceprogram?Click here to view page 1 of the table of areas under the standard normal curve.Click here to view page 2 of the table of areas under the standard normal curve.a.
