A nutrition study investigated knowledge about fruit juices. The study was conducted in a pediatric clinic. Accompanying parents were asked to classify a national brand of "fruit drink", that contains less than 10% fruit juice, as 100% fruit juice, fruit juice mix, or no fruit juice at all. The investigators asked 150 parents. The table contains the results. Juice Content 100% 1%-99% 0% Gender Gender Female Male 15 55 30 100 is many-sided. 15 25 10 50 Total 30 80 40 150 The null hypothesis tests whether females and males have the same conditional distributions regarding classifying juice content. If we ask whether the conditional probabilities classifying the drinks as 100% juice, 10% to 99% juice, or less than 10% juice are the same or different. The alternative tests whether they are different. Such an alternative: O is two-sided. O is one-sided. O cannot be determined from the information given.

The null hypothesis tests whether females and males have the same conditional distributions regarding classifying juice content.
If we ask whether the conditional probabilities classifying the drinks as 100% juice, 10% to 99% juice, or less than 10% juice are
the same or different.
The alternative tests whether they are different. Such an alternative:
is many-sided.
is two-sided.
is one-sided,
cannot be determined from the information given.
