25 pea pods were broken apart and the number of peas in each pod recorded. the record looked as foolows:
# of peas: 2,3,4,5,6 and frequency; 7,9,5,3,1
a. does this data appear to be skewed?
b. What is the model class for theis survey?
To determine if the data appears to be skewed and to identify the model class for the survey, we need to analyze the given frequency distribution.
a. To determine if the data appears to be skewed, we should examine the distribution of the number of peas per pod. If the data is symmetric around a central value, it is not skewed. However, if the data is not symmetric and there is a long tail on one side of the distribution, it is considered to be skewed.
Here, we have the number of peas on the x-axis and the frequency on the y-axis. Based on the given data, we have:
Number of peas: 2, 3, 4, 5, 6
Frequency: 7, 9, 5, 3, 1
To visualize this, we can create a bar graph:
Number of Peas (x-axis) | Frequency (y-axis)
---------------------------------------------
2 | 7
3 | 9
4 | 5
5 | 3
6 | 1
Looking at the bar graph, we can observe that the frequency is highest for the number of peas 3, followed by 2. As the number of peas increases, the frequency decreases. This suggests that the distribution is skewed to the right (positively skewed) because the longer tail is on the right side. Therefore, the data appears to be skewed.
b. The model class for this survey is not explicitly mentioned in the given information. However, based on the context, it seems that the survey is collecting data on the number of peas in each pod. Therefore, the model class for this survey could be "Number of Peas in a Pod."
