The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tested positive, given that he or she did not have the disease. The individual actually had the disease Yes No Positive 125 25 Negative 8 142 The probability is approximately (Round to three decimal places as needed.)

Elliot read a report from a previous year saying that 6% of adults in his city biked to work. He wanted to test - whether this had changed, so he took a random sample of 240 adults in his city to test Ho : p= 0.06 versus Ha : p + 0.06, where p is the proportion of adults in Elliot's city that bike to work. The sample results showed 24 adults who biked to work. Assuming that the conditions for inference have been met, identify the correct test statistic for Elliot's significance test.
