The following is data adapted from data provided on the Pohnpei Surf Club site. Like many television shows, this data is only based on real data. Actual test in Schoology.

Height (feet) 	Period (seconds)
0 	0
2 	4.7
3 	6.3
4 	12
5 	12
6 	13.5
6 	14
8 	16.3

1. What is the sample size for this data?
2. Calculate the slope. Round to two decimal places!
3. Calculate the y-intercept. Round to two decimal places!
4. Using the slope and intercept, calculate the predicted period for a height of 7 feet. Round to two decimal places.
5. Using the slope and intercept, calculate the predicted height for a period of 8.5 seconds. Round to two decimal places.
