You're curious if vehicle wheelbase affects the time it takes to parallel park a car. you set up an experiment where 50 people are timed while they parallel park two different cars: one with a short wheelbase and the other with a long wheelbase. the results of the experiment yield an average park time for the short wheelbase car of 32 seconds with a standard deviation of 8 seconds. the average park time for the long wheelbase car is 37 seconds with a standard deviation of 7 seconds. can you conclude that the time it takes to park a short wheelbase car is less than the time it takes to park a long wheelbase car?

Carla was trying to decide what to do saturday evening. she has $100 available to spend for the evening. she has narrowed her choices down to these events: braves game, a concert of an artist she likes, or the georgia aquarium. admission to the braves game is $25, hot dogs cost $10, sodas cost $5. the concert costs $25 for admission, $20 for a souvernir t-shirt, and $10 for a soda. the georgia aquarium has the show of a lifetime with an all you can eat and drink that costs $100. carla does not want to take any driving chances, so in addition to the cost of the aquarium, she will also need to pay for her uber/lyft, which is $15 each way. which option should carla choose if she wants to spend the least? based on that choice, what then is carla's oppotunity cost? fully explain your answer in at least one paragraph.
