Considering the situation described, the confidence interval is given by:
(0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.
Then, the bounds of the interval are given by:

Answer:
3/8
Step-by-step explanation:
4/8 = 1/2
Subtract the amount her son ate (1/2 or 4/8) from the total amount and you get 3/8.
<span>The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard deviation of 50. what is the probability that a student uses more than 580 minutes?
Given
μ=500
σ=50
X=580
P(x<X)=Z((580-500)/50)=Z(1.6)=0.9452
=>
P(x>X)=1-P(x<X)=1-0.9452=0.0548=5.48%

Answer:
The answer to your question is below
Step-by-step explanation:
See the picture below
Data
A (-2, 3)
B (4, 5)
I plotted the points C (4, 3) and D (-2, 5)
Distance
dAC = 
= 
= 6
dBD = 
= 
= 6
dAD = 
= 
= 2
dBC = 
dBC = 
dBC = 2
Total distance = dAC + dBD + dAD + dBC
Total distance = 6 + 6 + 2 + 2
= 16
I calculate the length of each side and then I sun them up.
