1 answer:
Question is incomplete Let assume the Slope = 2
Answer:
Therefore the Equation of line is
Step-by-step explanation:
Given:
Slope = 2 ( Assumption )
y-intercept = -3
To Find:
Equation of Line in Slope-intercept form
Solution:
Equation of Line in Slope-intercept Form is given as
Where,
So, substituting Slope =2 and y-intercept = -3 in above we get
Which is the Required Equation of line
Therefore the Equation of line is

Answer:
The 95% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level is (0.2087, 0.2507).
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:
Suppose a sample of 1537 tenth graders is drawn. Of the students sampled, 1184 read above the eighth grade level. So 1537 - 1184 = 353 read at or below this level. Then
95% 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 95% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level is (0.2087, 0.2507).
