K Historically, about 53% of the population of a certain country believed that the planet's temperature was rising ("global warming"). A March 2010 poll wanted to determine whether this proportion had changed. The poll interviewed 950 adults in the population, and 516 said they believed that global warming was real. (Assume these 950 adults represented a simple random sample.) Complete parts a through c below. H₂: p=0.53 O D. Ho: p>0.53 Ha: p<0.53 OE. Ho: p=0.53 Ha: p=0.53 Determine the z-test statistic, using the value for p from part a. Z= (Round to two decimal places as needed.) Find the p-value. p-value = Do you reject or not reject the null hypothesis? O Reject Ho- O (Round to three decimal places as needed.) Do not reject Ho. c. Choose the correct interpretation. OA. In 2010, the percentage of the population who believe global warming is real is significantly different from 53%. OB. In 2010, the percentage of the population who believe global warming is real has not changed from the historical level of 53%.
