Question 5. In the code cell below, create a visualization that will help us determine if there is an association between birth rate and death rate during this time interval. It may be helpful to create an intermediate table containing the birth and death rates for each state. (4 Points) Things to consider: • What type of chart will help us illustrate an association between 2 variables? • How can you manipulate a certain table to help generate your chart? • Check out the Recommended Reading for this homework! In [120]: # In this cell, use birth_rates and death_rates to generate your visualization birth_rates_2015 = pop . column( 'BIRTHS' ) / pop . column( '2015' ) death_rates_2015 = pop . column( 'DEATHS' ) / pop . column( '2015' ) birth_death = Table() . with_column( 'Birth Rates' , birth_rates_2015) . with_column( 'Death Rates' , d birth_death . scatter( 'Birth Rates' , 'Death Rates' ) 1

Question 2. Now, produce a histogram that visualizes the distribution of all ride times in Manila using the given bins. (4 Points) In [125]: equal_bins = np . arange( 0 , 120 , 5 ) manila . hist( 'ride time' , bins = equal_bins) # Don't delete the following line! plt . ylim( 0 , 0.05 ); 5

Question 6. Identify one difference between the histograms, in terms of the statistical properties. > Hint : Without performing any calculations, can you comment on the average or skew of each histogram? (4 Points) Boston has a higher percentage but we can’t comment on the average of each histogram because there isn’t enough information because it’s not specific like a scatter plot. 7

Question 2. State at least one reason why you chose the histogram from Question 1. Make sure to clearly indicate which histogram you selected (ex: “I chose histogram A because …”). (5 Points) I chose Histogram A because on both sides of the scatter plot most of the data points were between -2 all the way till 3. And in both clusters of data they meet or are plotted, more towards the middle. 11

Question 4. State at least one reason why you chose the histogram from Question 3. Make sure to clearly indicate which histogram you selected (ex: “I chose histogram A because …”). (5 Points) I just looked at the y values and there was not much data between -0.5 & 0.5 which is reflected in histogram b because of the gap in the middle 13
