In a Gallup poll conducted August 7–10, 2014, American adults aged 18 and older were asked, “If you were taking a new job and had your choice of a boss, would you prefer to work for a man or a woman?” Of the respondents, 33% said that they would prefer a male boss, 20% said a female boss, 46% said it would not make a difference to them, and 1% had no opinion (www.gallup.com). Suppose these results are true for the 2014 population. Recently, 1500 randomly selected American adults were asked the same question. The following table contains the frequency distribution that resulted from this survey

Test at the 1% significance level whether the current distribution of opinions is different from the 2014 distribution.
