National statistics show that 23% of men (sample 1) smoke and 18.5% of women (sample 2) do. A random sample of 149 men indicated that 64 were smokers, and of 119 women surveyed , 41 indicated that they smoked. Construct a 95% confidence interval for the true difference in proportions of male and female smokers. Select one: a. -o.032

A survey asked, "How many tattoos do you currently have on your body?" Of the 1228 males surveyed, 176 responded that they had at least one tattoo. Of the 1072 females surveyed, 147 responded that they had at least one tattoo. Construct a 95% 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 p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for P₁-P2- The lower bound is The upper bound is (Round to three decimal places as needed.) H Vi Vi More X
The figure to the right shows the results of a survey in which 997 adults from Country A, 1022 adults from Country B, 1013 adults from Country C, 1011 adults from Country D, and 1008 adults from Country E were asked whether national identity is strongly tied to birthplace.

In a study investigating the difference in food preferences between men and women, researchers asked subjects to indicate whether they liked or disliked certain foods. One question was about liking cabbage. Twenty percent of a sample of 75 men liked cabbage, while 41% of a sample of 100 women indicated that they liked cabbage. Provide two confidence intervals, one for the proportion of men who like cabbage and one for the proportion of women who like cabbage. Use a 95% confidence level. State whether or not the populations are different and explain how you know this.
