In marketing, response modeling is a method for identifying customers most likely to respond to an advertisement. suppose that in past campaigns 31.6% of customers identified as likely respondents did not respond to a nationwide direct marketing campaign. after making improvements to their model, a team of marketing analysts hoped that the proportion of customers identified as likely respondents who did not respond to a new campaign would decrease. the analysts selected a random sample of 1500 customers and found that 441 did not respond to the marketing campaign. the marketing analysts want to use a one‑sample ‑test to see if the proportion of customers who did not respond to the advertising campaign, has decreased since they updated their model. they decide to use a significance level of =0.05 determine the p? value for this test. give your answer precise to at least three decimal places.
