Answer:
(b) 0.3 microns or larger
Step-by-step explanation:
A particle of size 0.3 microns is judged to be the most penetrating particle size. So, a rating for the filtering of those particles will be a worst-case rating. For particles of any other size, the filter will perform better than for 0.3 micron particles. HEPA filters are rated based on their performance with particles ...
0.3 microns or larger
Answer:
Option D
Step-by-step explanation:
A type I error occurs when you reject the null hypothesis when it is actually true.
The null hypothesis in this case is minimum breaking strength is less than or equal to 0.5.
A type one error would be allowing the production process to continue when the true breaking strength is below specifications.
Step-by-step explanation:
straight angle a + 117 = 180
a = 180 - 117
= 63
total angle in triangle = 180
63 + b + 81 = 180
b = 180 - 63 - 81
= 36
