Te speeds of two types of drones in reaching a target from

the same distance are compared. Te owner of drone A claims that it reaches the

target faster than drone B from the other type. Te speeds are measured 5 times

from the same distance. Let X be the number of times that drone A reached the

target faster than drone B. When the rejection region is { 5 X = }, answer the

following questions:

a. If the probability that drone A is faster than drone B is

p, fnd the distribution of X.

b. State the testing hypotheses.

c. Find the probability of a type I error.

d. When the
