Answer:
0.2288
Step-by-step explanation:
This is straightforward.
What we need to do is to divide the number of defective semiconductor chips over the total number of semiconductor chips.
Initially, the total number of semi conductor chips is 119 and the total number of defective semiconductor chips is 28.
After the first selections , we can infer that the total number of semiconductor chips is 118 while the number of defective ones is 27.
Hence on the second drawing, the probability that he will
Select a defective one is 27/118
Answer:
(a) there is a little difference in proportion clearly from the data given as observed.
(B) if a conclusion In the test part (a) is incorrect then a type 1 error was made.
Step-by-step explanation:
