The average weight of a population of manatees is unknown. A random sample of manatees selected from the population yields a sample mean of x¯=880.3 pounds. Assume the sampling distribution of the mean has a standard deviation of σx¯=10.4 pounds. Use the Empirical Rule to construct a 68% confidence interval for the true population mean weight.
The confidence interval that we have for the population mean is given as [869.9 , 890.7]
How to solve for the confidence intervalThe confidence interval is the range of values that, if you repeated your experiment or resampled the population in the same manner, you would anticipate your estimate to fall within a specific proportion of the time.
We have the following data that we have to solve this problem with
The mean = x¯=880.3 pounds
The standard deviation = 10.4 pounds.
The confidence interval = 68%
To get the confidence interval for the true mean of the population weight we would have
mean ± standard deviation
880.3 ± 10.4
The interval would be written out as
880.3 - 10.4 and 880.3 + 10.4
the confidence interval =
[869.9 , 890.7]

9. The sum of two numbers is 130 and their difference is 34. Let x be the first number and y be the second
number. Set up a system of equations and use the elimination method to find the numbers. You must
show your work.
Using the system of equations and use the elimination method the two numbers are 82 and 48.
What is the elimination method?
To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are equal.
Here, we
let the first number = x
let the second number = y
according to the given conditions:
x + y = 130 ........(1)
x - y = 34 .........(2)
Using the elimination method we add both equations (1) and (2) and we get
2x = 164
x = 164/2 = 82
Now, we substitute the value of x in eq (1) and we get
82 + y = 130
y = 130-82
y = 48
Hence, using the system of equations and use the elimination method the two numbers are 82 and 48.

Step-by-step explanation:
He already has $13.70 (7.40+6.30) saved up so you have to subtract that from 18.60 to find the total Ace needs to save up.
18.60-13.70=4.90
To check your answer, you can add 7.40, 6.30, and 4.90 and see if you get a total of 18.60.

A doctor wants to estimate the mean HDL cholesterol of all 20- to 29-year-old females. How many subjects are needed to estimate the mean HDL cholesterol within 4 points with 99% confidence assuming S=13.8 based on earlier studies? Suppose the doctor would be content with 90 confidence. How does the decrease in confidence affect the sample size required?
The way the decrease in confidence affect the sample size required is: A. Decreasing the confidence level decreases the sample size needed.
How to find the sample size ?Using this formula to find the decrease in sample size
n = [zs/E]^2
Where:
n = Sample size
zs = z-score
E= margin of error
Confidence coefficient for 99% = 2.58
Hence,
2.58 × 13.8/sqrt(n) = 0.04
2.598 × 13.4 /0.04 = sqrt(n)
( 2.598× 13.8 /0.04)^2 = n
n=803,371.6
So,
Confidence coefficient for 90% = 1.64
n= (1.64× 13.8/0.04)^2
n =320,129.64
Therefore the correct option is A.

The fraction of the patients that have a waiting time of more than 7 minutes found by using the area under the curve is 269/312
What is a fraction in mathematics?A fraction indicates the quantitative comparison showing the number of times one quantity is contained in another quantity.
The area under the frequency curve is found as follows;
Dividing the area into composite shapes of a rectangle, triangle and trapezoid, we get;
(9.2 - 5.5) × 4 + (4 + 2)×3/2 + (2.5 + (9.2 - 5.5)) × 1/2 + (2.5 + 1.2) × 2/2 + 1.2 × 1/2 = 31.2
The area for those that have a waiting time of more than 7 minutes is therefore;
(9.2 - 5.5) × 4 + (4 + 2)×3/2 + (2.5 + (9.2 - 5.5)) × 1/2 = 26.9
The fraction that have a waiting time of more than 7 minutes is therefore;
26.9/31.2 = 269/312 ≈ 0.862
The fraction of the patients that have a waiting time of more than 7 minutes is 269/312

(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of buckets of popcorn and the other axis to represent the number of drinks.
(b) Explain your graph.
The equation of the relationship is 2x + 4y = 45 and the graph is attached
How to sketch the graph?From the question, we have the following parameters:
Amount = $45Price of each bucket of popcorn = $4Price of each drink = Half the price of each bucket of popcornThis means that
Price of each drink = Half $4
Evaluate
Price of each drink = $2
Represent the number of drinks with x and the number of bucket of popcorn with y
So, we have the following representation
Total amount of popcorn + Total amount of drinks = Total amount
This gives
2x + 4y = 45
Next, we sketch the graph
