Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
Number of pounds = 8
Cost of bananas = $3.12
Unit rate would be
Number of pounds = 9
Cost of bananas = $3.06
Unit rate would be
Difference between two unit rates would be
so, the rate for the first store is $0.05 per pound more than the second store.
Hence, Third option is correct.

Answer:
As a rule of thumb, it is usual to define discrete data in 5 to 10 groups or bins. When graphed, the height of each group or bin defines the frequency for the group or bin.
Explanation:
When discrete data is graphed into a histogram, it defines a frequency distribution. Because information becomes lost when too many groups or bins are used, it is customary to use 5 to 10 bins.
Example:
Consider the following random data which has a sample size of 16.
x = [1, 3, 6, 2, 9, 8, 4, 5, 10, 3, 5, 4, 3, 5, 7, 5]
When fewer groups or bins are used to construct the histogram, the centralized nature of the distribution is easy to discern.
As the number of bins increases, the distribution becomes more difficult to define.
