I’m pretty sure it would be C
This is an incomplete question, here is a complete question.
What is a peregrine falcon's maximum speed while diving to catch prey 200 miles per hour in feet per second? (Round your answer to the nearest whole number. (1 mile = 5280 feet)
Answer : The speed in feet per second is, 293 feet/s
Step-by-step explanation :
As we are given that the speed of peregrine falcon's is 200 miles per hour. Now we have to determine the speed in feet per second.
As we know that:
1 mile = 5280 feet
1 hour = 3600 second
So,
1 mile/hr = 1.4667 feet/s
As, 1 mile/hr = 1.4667 feet/s
So, 200 mile/hr = 
= 293.34 feet/s ≈ 293 feet/s
Therefore, the speed in feet per second is, 293 feet/s

Answer:
196
Step-by-step explanation:
Given that the significance level of 2% = α
Because the the null hypothesis is true so it is denoted by α it also defined as the level of significance =1 - confidence level = 1 - 0.02 = 0.98.
So the number of the tests will incorrectly find significance:
=0.98×200=196
