Answer:
And rounded up we have that n=1068
Step-by-step explanation:
We have the following info given:
the confidence level desired
represent the margin of error desired
The margin of error for the proportion interval is given by this formula:
(a)
The confidence level is 95% or 0.95, the significance is and the critical value for this case using the normal standard distribution would be
Since we don't have prior information we can use as an unbiased estimator
Also we know that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Answer:
It is a many-to-one relation
Step-by-step explanation:
Given
See attachment for relation
Required
What type of function is it?
The relation can be represented as:
Where
and
Notice that the range has an occurrence of 10 (twice)
i.e.
and
In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
