take your survey data and code the gender question as Male=0 and Female=1. Suppose we hypothesize that women are more likely to respond to surveys than men are. Specifically, we believe that more than 55 percent of all respondents are women (this equates to the proportion of the gender variable to be greater than 0.55). Use the methods learned this week to test this hypothesis. Males participated in the survey are 24. The number of females are 26. Make sure...

The market researchers at Barton’s pizza are interested in the proportion of male customers and female customers that would be willing to try a new pizza. Random samples of 176 males and 124 females were randomly selected. Responses were recorded as Yes (i.e. interested) or No (i.e. not interested) and are listed as variables MalesInterested (1) and FemalesInterested (2). The samples indicated that 91 males and 59 females respectively were interested in trying a new pizza. Test that the proportion...

A survey asked, "How many tattoos do you currently have on your body?" Of the 1211 males surveyed, 193 responded that they had at least one tattoo. Of the 1089 females surveyed, 147 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. Let P, represent the...
