(Solved): in python Task-2: Define a function named plot_serial_numbers to make a histogram of any dataframe ...

Task-2: Define a function named plot_serial_numbers to make a histogram of any dataframe of serial numbers. It should take one argument, a dataframe like obs with one column named serial number. It should plot a histogram of the values in the column using bins of width 10 ranging from 1 to 170 but return nothing. Also, the plot must display appropriate \( x \)-label, y-label, and title. Then, call that function to make a histogram of the serial numbers in the column serial number of the dataframe obs Task-3: Calculate the statistical estimate of \( N \) as twice the mean of the observed serial numbers located in the column serial number of the dataframe obs and store it in a variable named obs_mean_estimate. Print obs_mean_estimate to the output. Task-2: Define a function named plot_seria1_numbers to make a histogram of any dataframe of serial numbers. It should take one argument, a dataframe like obs with one column named serial number. It should plot a histogram of the values in the column using bins of width 10 ranging from 1 to 170 but retum nothing. Also, the plot must display appropriate x-label, y-label, and title. Then, call that function to make a histogram of the serial numbers in the column serial number of the dataframe obs Task-3: Calculate the statistical estimate of \( \mathrm{N} \) as twice the mean of the observed serial numbers located in the column serial number of the dataframe obs and store it in a variable named obs_mean_estimate. Print obs_mean_estimate to the output.
