Of the 566 female respondents who answered the question, 40% strongly agreed that a working mother does not hurt children. What is the 90% confidence interval for this statistic?

0.74 to 0.86

0.37 to 0.43

Though 70% of women with children younger than 18 years participate in the labor force, society still upholds the stay-at-home mother as the traditional model. Some believe that employment distracts mothers from their parenting role, affecting the well-being of children.

Of the 435 male respondents who answered the question, 18% strongly agreed that a working mother does not hurt children.

As our confidence in the result increases, how does the size of the confidence interval change?

The confidence interval gets wider, not narrower - increasing confidence leading to less precise intervals.

The confidence interval gets narrower, but not wider - decreasing confidence leading to more precise intervals.

As the result increases, the confidence level remains the same.

As the result increases, the confidence level is reduced.
