.
9.	Eight (8) tourists were asked about the airfare expenses 
and their total budgeted amount in their last travel/holiday.
Air fare (in $) 	200 	300 	250 	100 	150 	170 	180 	230 
Total Budget (in $) 	2500 	2800 	2100 	1200 	1800 	1900 	2000 	2700 


a).  Draw the scatter plot and the line of best fit. What is the expected budget 
for an individual of this group if the airfare to a certain city of her choice 
is $220? And what is the expected airfare if her budget is $3,000?

b). Determine if there is a correlation between the two variables with the 
assumption that all travel costs are determined by the travellers’ economic 
status. Describe the correlation strength, provide your conclusion, and 
practical recommendations for the airline industry.
