Answer:
"A Type I error in the context of this problem is to conclude that the true mean wind speed at the site is higher than 15 mph when it actually is not higher than 15 mph."
Step-by-step explanation:
A Type I error happens when a true null hypothesis is rejected.
In this case, as the claim that want to be tested is that the average wind speed is significantly higher than 15 mph, the null hypothesis has to state the opposite: the average wind speed is equal or less than 15 mph.
Then, with this null hypothesis, the Type I error implies a rejection of the hypothesis that the average wind speed is equal or less than 15 mph. This is equivalent to say that there is evidence that the average speed is significantly higher than 15 mph.
"A Type I error in the context of this problem is to conclude that the true mean wind speed at the site is higher than 15 mph when it actually is not higher than 15 mph."

Answer:
area = 160160 inches²
area = 1.6016 × 10⁵ inches²
Step-by-step explanation:
The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .
The area of the rectangular computer chip is the product of the length and the width.
area = length × width
area = (22 × 10) × (7 × 104)
area = 220 × 728
area = 160160 inches²
In scientific notation
area = 1.6016 × 10⁵ inches²
160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
