Application Peace Valley Park Boat Rentals make
the same average amount of profit on Saturday and Sunday
Peace Valley Park Boat Rentals rent out the same amount of average boats on Saturday and Sunday.
![Page 27: Peace Valley Boat Rental Statistics](https://reader036.vdocuments.us/reader036/viewer/2022062814/56816866550346895ddec38f/html5/thumbnails/27.jpg)
Bias/Errors Incomplete or inaccurate records Weather not taken into consideration
Considerably less people rent boats when the weather is bad
Not completely randomNot all records available
Does not only rent boatsIt sells boat permits and moorings
![Page 28: Peace Valley Boat Rental Statistics](https://reader036.vdocuments.us/reader036/viewer/2022062814/56816866550346895ddec38f/html5/thumbnails/28.jpg)
Personal Opinions/Conclusions I thought the project was overall hard and tedious It was very surprising to find out that the average
profits and the average total boats rented out on Saturday and Sunday were the same. We thought Sunday would be busier
I think more time would have been better, especially for our topic because there were a lot of papers that we had to go through
Overall the project was a good learning experience about the Peace Valley Park Boat Renting Place and its business
