Tim purchased a random sample of clementines at a local grocery store. The 95% confidence interval for the mean weight of all clementines at the store is 76.6 grams to 90.1 grams. Interpret this confidence interval.
Answer:
Step-by-step explanation:
Confidence interval is constructed to provide an estimated for an unknown population parameter such as the mean and sometimes, the standard deviation. It is expressed as
Sample mean ± margin of error
From the confidence interval given, the lower boundary is 76.6 grams while the upper boundary is 90.1 grams. Therefore,
It means that we are 95% confident that the mean weight of all clementines at the store lies between 76.6 grams to 90.1 grams. Also, 95% of the confidence intervals constructed in this way would contain the true value for the population mean weight of all clementines at the store.
Final answer:
A 95% confidence interval for the mean weight of clementines at a local grocery store ranging from 76.6 to 90.1 grams means we are 95% confident the true average weight of all clementines falls within this range. This range is based on a random sample and provides an estimate of the population mean. The width of the interval reflects the estimate's precision.
Explanation:
A 95% confidence interval for the mean weight of clementines, which ranges from 76.6 grams to 90.1 grams, means that we are 95% confident that the average weight of all clementines available in the store falls within this range. This interval was determined based on a random sample of clementines purchased, which serves as a representative subset of the entire clementine population in the store.
The concept of a confidence interval allows researchers and statisticians to estimate the true mean of a population based on sample data. In this case, unless the true average weight of the clementines lies outside this range, which has only a 5% probability (100% - 95%), we can assume that our interval includes the true mean weight of all clementines in the store. This interpretation is common in statistics and is crucial for making informed decisions or predictions based on sample data.
The width of the confidence interval, from 76.6 to 90.1 grams, reflects the precision of our estimate. A narrower interval would indicate a more precise estimate of the true mean weight, but increasing precision usually requires a larger sample size or a more homogeneous population. The principles behind confidence intervals are fundamental in various fields, including scientific research, engineering, and business analytics, to make reliable inferences about population parameters based on sample statistics.
Which relation describes a function?

{(2,-1), (2, 1), (3,-1), (3, 1)}
{(2, 2), (2, 3), (3, 2), (3, 3)}
Answer:
{(-2, -3), (-3, -2), (2,3), (3, 2)}
Step-by-step explanation:
A function is a set of ordered pairs in which no two pairs have the same first number.
In other words, an x cannot be paired with two y's.
A function takes an x and pairs it with one and only one y.
{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.
{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.
{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

PQ⊥PS , m∠QPR=7x−9, m∠RPS=4x+22
Find : m∠QPR
Given:
It is given that,
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the value of ∠QPR.
Formula
As per the given problem PR lies between PQ and PS,
So,
∠QPR+∠RPS = 90°
Now,
Putting the values of ∠RPS and ∠QPR we get,
[tex]7x-9+4x+22 = 90[/tex]
or, [tex]11x = 90-22+9[/tex]
or, [tex]11x = 77[/tex]
or, [tex]x = \frac{77}{11}[/tex]
or, [tex]x = 7[/tex]
Substituting the value of [tex]x = 7[/tex] in ∠QPR we get,
∠QPR = [tex]7(7)-9[/tex]
or, ∠QPR = [tex]40^\circ[/tex]
Hence,
The value of ∠QPR is 40°.
Divide the sum of 3/4 and −4/7 by their difference
Answer:
5/37.
Step-by-step explanation:
Sum:
3/4 + -4/7
= 21/28 - 16/28
= 5/28
Difference:
3/4 - (-4/7)
= 3/4 + 4/7
= 21/28 + 16/28
= 37/28.
Dividing:
5/28 / 37/28
= 5/28 * 28/37
= 5/37.
One zip Weighs as much as three zaps two zaps weight as much as five zowies three zowies weigh as much as two swooshes if one weighs sixty pounds how much does a zip weigh
Answer:1 zip weighs 30 lb
Step-by-step explanation:
3 zowies = 12 lb. so, 1 zowie = 4 lb.
2 zap = 20 lb. so, 1 zap = 10 lb.
1 zip = 30 lb.
One zip weighs 360 pounds.
1. One zip weighs as much as three zaps.
2. Two zaps weigh as much as five zowies.
3. Three zowies weigh as much as two swooshes.
4. One swoosh weighs 60 pounds.
We need to find the weight of one zip.
Step 1: Find the weight of one swoosh.
Since one swoosh weighs 60 pounds, we have:
1 swoosh = 60 pounds
Step 2: Find the weight of three zowies.
Since three zowies weigh as much as two swooshes, and one swoosh weighs 60 pounds, we have:
3 zowies = 2 swooshes = 2 * 60 = 120 pounds
Step 3: Find the weight of two zaps.
Since two zaps weigh as much as five zowies, and three zowies weigh 120 pounds, we have:
2 zaps = 5 zowies = 120 pounds
Step 4: Find the weight of one zip.
Since one zip weighs as much as three zaps, and two zaps weigh 120 pounds, we have:
1 zip = 3 zaps = 3 * 120 = 360 pounds

Therefore, to find the number of cubes it takes to fill the prism, we divide the volume of the prism by the volume of the cube.
[tex]\text{Volume of Prism/Volume of Cube}=4 \div \dfrac{1}{27}\\=4 X 27 \\=108[/tex]

Okay, we are going to solve this backwards!
First, we need to know that the formula for circumference is
c = π × d
d = diameter
π = 3.14
They told us what the circumference is, so let's plug it in
75 = (3.14) × (d)
let's solve for d
[tex]\frac{75}{3.14} = d[/tex]
d = 23.88 inches
We must remeber that the radius is HALF of the diameter, so let's divide the diameter by 2
[tex]\frac{23.88}{2} = 11.94[/tex]
Now, let's round to the nearest whole inch like they suggested
11.94 ≈ 12
The answer is 12 inches!
