Question
![**Cost of Student Groceries**
The histogram displays the distribution of the cost of groceries purchased by students. The x-axis is labeled "Cost ($)" and ranges from $40 to $100. The y-axis is labeled "Frequency" and ranges from 0 to 7.
The bars in the histogram represent different cost intervals:
- $40-$50: Frequency of 1
- $50-$60: Frequency of 2
- $60-$70: Frequency of 4
- $70-$80: Frequency of 7
- $80-$90: Frequency of 3
- $90-$100: Frequency of 1
**Questions:**
a. Is this graph symmetric or skewed? [_____]
b. For this graph, is mean or median the best choice for the measure of center? [_____]
c. For this graph, is standard deviation or IQR the best choice for the measure of variation? [_____]
d. For this graph, the mean is expected to be [_____] (higher than, lower than, or about the same as?) the median.](https://content.bartleby.com/qna-images/question/bddd883b-3662-467b-8d41-3191ae58ea32/c1b90b16-c216-4156-8b27-2eafd834f27a/mevg5g_processed.png)
