Answer:
a. .92
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 
.
The margin of error of the interval is:
The lower bound is the point estimate subtracted by the margin of error.
The upper bound is the point estimate added to the margin of error.
Point estimate:
The confidence interval is symmetric, so it is the mean between the two bounds.
In this problem:
Sample of 400, which means that 
Margin of error is the estimate subtracted by the lower bound. So 
We have to find z.
has a pvalue of 0.96.
This means that:
Confidence level:
So the correct answer is:
a. .92
UNDEFINED terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. <span>DEFINED terms can be combined with each other and with undefined terms to define still more terms.</span>
The expression of the unit rate was defined with all parameters rightly inputed the Molly's unit rate is 2.5 pages per minutes
<h3>Speed and Rate</h3>
Given Data
- Number of Pages read = 75 pages
The speed/ rate is defined as the number of pages read per minutes passed
Hence the expression for the unit rate is given as
Unit Rate = Number of pages/Time Taken
Substituting our given Parameters
Unit Rate = 75/30
Unit Rate = 2.5 pages per minutes
