To determine the estimated mode of the number of peas in the pea pods based on Amanda's random selection of 18 pods, we need to consider that the mode is the number that appears most frequently in a dataset.
From your provided responses (8, 8.5, 9, and 10), it seems that the estimated mode might be around 8 or 9, assuming these are common values that appeared in her counts. However, the exact distribution of counts in her sample is necessary to make an accurate estimation.
Since the majority of pea pods typically have a higher frequency of certain counts of peas, and without further data, it's reasonable to conclude that a common number, such as 8 or 9 peas, might be the mode.
Given that there are no additional details on the specific counts Amanda recorded, if we are to assume that the mode is the number that occurs with the highest frequency, 8 would likely be the best estimate among the options provided, as it can typically be a common count in many pea pods.
The estimated mode of the number of peas to be found in all the pea pods is 8.
