Answer:
The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, 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:
560 random tests conducted, 26 employees failed the test. This means that
98% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).
Answer:
- Trinomials in the form
can often be factored as the product of two binomials.
Step-by-step explanation:
As we know that a polynomial with three terms is said to be a trinomial.
Considering the trinomial of a form
As
a = 1
so
- Trinomials in the form
For example,
Therefore, Trinomials in the form can often be factored as the product of two binomials.
Answer:
9
Step-by-step explanation:
Using the rule of radicals
×
⇔
Simplify the radicals
=
= ×
= 2
=
= ×
= 3
Then
3 +
= 3(2 ) + 3
= 6 + 3
= 9
