Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point a:
In this sense, describe what type of error I will be.
Type I error: to conclude that perhaps the mean bulb life would be less than three hours when it becomes (at least) 3 hours.
In point b:
Describe throughout this context what the Type II error becomes.
An error of type II: never assuming that its bulbs' mean lifetime is much less than 3 hours. three hours at least
In point c:
What error — type I and type II — would further impact the interaction between the manufacturer and the customer?
A Type II error is probably further problematic because it means that even the buyer will buy bulbs that do not last long.

Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
(11)
- 81 + x² = - y² ( add y² to both sides )
- 81 + x² + y² = 0 ( add 81 to both sides )
x² + y² = 81 ← in standard form
with centre = (0, 0 ) and r = 
= 9
(12)
y² + x² - 196 = 0 ( add 196 to both sides )
x² + y² = 196 ← in standard form
with centre = (0, 0 ) and r = 
= 14
