Final answer:
To find the upper quartile, arrange the data in ascending order, find the median of the upper half of the data set.
Step-by-step explanation:
To find the upper quartile for a given data set, we need to first arrange the data in ascending order. The data set in this case is {7, 5, 10, 5, 5, 6, 3, 5, 5, 4, 3}. When we arrange it in ascending order, we get {3, 3, 4, 5, 5, 5, 5, 5, 6, 7, 10}. Next, we find the median (middle value) of the upper half of the data set. Since we have 11 data points, the upper half starts at the 6th data point, which is 5. This is the upper quartile for the given data set.
