According to a study conducted for Gateway Computers, 54% of men and 72% of women say that weight is an extremely/very important factor in purchasing a laptop computer. Suppose this survey was conducted using 326men and430women. Do these data show enough evidence to declare that a significantly higher proportion of women than men believe that weight is an extremely/very important factor in purchasing a laptop computer? Use a 5% level of significance. (Round the intermediate values to 3 decimal places, e.g. 0.785. Round your answer to 2 decimal places, e.g. 0.75.) Observedz=?
