A study of a local high school tried to determine the mean amount of money that each student had saved. The study surveyed a random sample of 96 students in the high school and found a mean savings of 4000 dollars with a standard deviation of 500 dollars. Determine a 95% confidence interval for the mean, rounding all values to the nearest whole number.
I don't know sorry I will try and come back If I get it :D
A 95% confidence interval for the average is 4100
What is confidence interval ?The confidence interval formula is used in statistics for describing the amount of uncertainty associated with a sample estimate of a population parameter. It is used to describe the uncertainty associated with a sampling method.
Formula of confidence interval:
If n ≥ 30,
Confidence Interval = m ± [tex]z(\frac{SD}{\sqrt{n} } )[/tex]
where,
n = Number of terms
m = Sample average
SD = Standard Deviation
z = Value corresponding to confidence interval in z table
Table of Confidence interval and Z
CI z
0.70 1.04
0.75 1.15
0.80 1.28
0.85 1.44
0.90 1.645
0.92 1.75
0.95 1.96
0.96 2.05
0.98 2.33
0.99 2.58
According to the question
random sample of student (n) = 96
average savings = 4000 dollars
Standard deviation = 500 dollars
95% confidence interval for the average needed
i.e , z = 1.96
Now, By using Formula of confidence interval:
Confidence Interval = m ± [tex]z(\frac{SD}{\sqrt{n} } )[/tex]
substituting the values
Confidence Interval = 4000 ± [tex]1.96(\frac{500}{\sqrt{96} } )[/tex]
= 4000 ± 100.021
= 4100.21
values to the nearest whole number
Confidence Interval = 4100
Hence, A 95% confidence interval for the average is 4100 .

Answer:
y = 6/5x - 24/5
Step-by-step explanation:
The two points we are given are (4, 0) and (9, 6). First, find the slope.
m = 6 - 0/9 - 4 = 6/5
Next, insert the values into the point-slope form formula. I'll use (4, 0) as the coordinates.
y - 0 = 6/5(x - 4)
y = 6/5x - 24/5
