The lottery commission in a certain state wanted to know if there was a significant difference in the proportion of men who played the lottery and the proportion of women who played the lottery. The 99% confidence interval to estimate pM - pW is given by (0.0823, 0.1177). What can be concluded from this 99% confidence interval?
All of the plausible values are positive, which is evidence that the proportion of men who play the lottery is greater than the proportion of women who play the lottery.
All of the plausible values are negative, which is evidence that the proportion of men who play the lottery is greater than the proportion of women who play the lottery.
The interval contains zero, which is evidence that the proportion of men who play the lottery is significantly different from the proportion of women who play the lottery.
The interval contains zero, which is evidence that the proportion of men who play the lottery is not significantly different from the proportion of women who play the lottery.
The interval does not contain zero, so no useful information can be garnered from this interval.
