There is a 99% chance that the true mean intended number of science courses for males is directly in the middle of these two values.
O There is a 99% chance that the true difference between the mean intended number of science courses for males and the mean intended number of science courses for females is directly in the
middle of these two values.
We are 99% confident that the true difference between the mean intended number of science courses for males and the mean intended number of science courses for females is between these
two values.
We are 99% confident that the true mean intended number of science courses for females is between these two values.
We are 99% confident that the true mean intended number of science courses for males is between these two values.
Based on your interval, how would you answer the question posed at the beginning of the exercise?
Zero is not included in the interval, which tells us that we can be confident that girls are inclined to enroll in fewer science courses than boys.
O Zero is not included in the interval, which tells us that we can be confident that girls are not inclined to enroll in fewer science courses than boys.
