The annual Waikiki Rough Water Swim contest is held over a 2.4-mile course and attracts approximately 1000 swimmers each year. Before the race, a random sample of the current velocity (in knots) along the race course is obtained, and the resulting information is used to determine whether the race should be cancelled. A mean current velocity, μ, of more than 0.65 knots is considered unsafe. The null and alternative hypotheses are as follows:
Null hypothesis H₀: The mean current velocity is not more than 0.65 knots.
Alternative hypothesis Hₐ: The mean current velocity is more than 0.65 knots.

Interpret the Type I error in this context.
