Suppose a scheduled flight must average at least 60% occupancy to be profitable. A sample of 120 flights on a particular route w
as studied: the mean occupancy rate per flight was 58% with a sample standard deviation of 11%. We would like to find out if there is sucient evidence to support a claim that this flight route is unprofitable. a) In terms of this problem, what is the Type I error? b) Define and find ↵. c) In terms of this problem, what is the Type II error? d) Define and find when the true mean occupancy rate is 0.62. e) Find the p-value associated with this test. What would you conclude at the 0.10 level

Answer:
Option B.
Step-by-step explanation:
It is given that ΔSRQ is a right angle triangle, ∠SRQ is right angle.
RT is altitude on side SQ, ST=9, TQ=16 and SR=x.
In ΔSRQ and ΔSTR,
(Reflexive property)
(Right angle)
By AA property of similarity,
Corresponding parts of similar triangles are proportional.
Substitute the given values.
On cross multiplication we get
Taking square root on both sides.
The value of x is 15. Therefore, the correct option is B.
