2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Is it reasonable to conclude that the data come from a population that is normally distributed?
O A. Yes, because the plotted values are not linear.
O B. No, because the plotted values are not linear.
O C. No, because there are not enough values to make a determination.

(c) Construct and interpret a 95% confidence interval for the mean age at which a baby first crawls. Select the correct choice and fill in the answer boxes to complete
your choice.
(Round to one decimal place as needed.)
O A. The lower bound is
weeks and the upper bound is
weeks. We are 95% confident that the mean age at which a baby first crawls is within the
confidence interval.
O B. The lower bound is
weeks and the upper bound is
weeks. We are 95% confident that the mean age at which a baby first crawls is outside of the
confidence interval.
