Answer:
The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.
Step-by-step explanation:
We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.
Let us find the sample score that corresponds to z-score of bottom 4%.
From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.
Upon substituting these values in z-score formula we will get our sample scores (x) as:
Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.
Now let us find sample score corresponding to z-score of 1.75 as upper limit.
Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected

The answer is B. it is caused by weather change
Answer:
Part A: 100%
Part B: 50%
Step-by-step explanation:
The difference between 10 and 5 is 5
5 is 100% of 5, so 10 is 100% greater than 5 (part A)
5 is 50% of 10, so 5 is 50% less than 10 (part B)
Part A is 100%, and Part B is 50%
