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.

Answer:
IQR = 5
Step-by-step explanation:
the IQR is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box plot , that is
Q₃ = 51
Q₁ is the value at the left side of the box plot , that is
Q₁ = 46
then
IQR = Q₃ - Q₁ = 51 - 46 = 5
The chance is 1/3 you will
Answer:
Average = 59.6667
Step-by-step explanation:
If Crane's average score on the first 2 tests was 85, we know that the sum of these both tests' score is 85 * 2 = 170.
Now, we sum the score of the third test, which is 9, so we have now 3 tests, and the sum of the scores is 170 + 9 = 179.
Calculating the new average, we divide the sum of the scores by 3, because now we have 3 tests instead of 2, so:
Average = 179 / 3 = 59.6667
