Answer:
(0.4062, 0.5098)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
For this problem, we have that:
356 dies were examined by an inspection probe and 163 of these passed the probe. This means that 
and 
Assuming a stable process, calculate a 95% (two-sided) confidence interval for the proportion of all dies that pass the probe.
So 
= 0.05, z is the value of Z that has a pvalue of ![1 - \frac{0.05}{2} = 0.975[tex], so [tex]z = 1.96](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7B0.05%7D%7B2%7D%20%3D%200.975%5Btex%5D%2C%20so%20%5Btex%5Dz%20%3D%201.96)
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is
(0.4062, 0.5098)
65.0798 rounded to the nearest tenth is 65.1, if the number after the number you are rounding is 5 or over you will round up. If the number after it is under 5 then it will stay the same.
The symbol to show that there are parallel lines is normally just a set
of vertical lines. Although if these are being drawn on a page and need
to be labelled as part of a shape or diagram, sometimes arrows will be
used to show they are parallel - either one arrow in the middle of the
line, or two arrows to show they are parallel but in different
directions.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Given the rational expression: 
, to express this in simplified form, we would need to apply the concept of partial fraction.
Step 1: factorise the denominator
Thus, we now have: 
Step 2: Apply the concept of Partial Fraction
Let,
= 
Multiply both sides by (x - 1)(x - 4)
= 
Step 3:
Substituting x = 4 in
Substituting x = 1 in
Step 4: Plug in the values of A and B into the original equation in step 2
