(Hypothetical.) Suppose five measurements of the volume of a liquid yield the following data (in milliliters).
52 48 49 52 5.3
Assume that the different measurements are due only to measurement error, and that measurement error is Normally distributed. The goal is to set up an approximate 95% confidence interval for the correct measurement. In each part, answer correct to three decimal places. First find the average and SD of the data. Calculator welcome and recommended. Average of the data: SD of the data (remember, it's a small sample): Estimate the correct measurement. Attach a give-or-take value to the estimate (that is, estimate the standard error). There are 5 measurements. If measurements follow a Normal distribution (e.g., if they vary only due to chance measurement error), then the standardized average of 5 measurements follows a Student t-distribution with So, for 95% confidence, we include our estimate. degrees of freedom. standard error(s) on each side of An approximate 95% confidence interval for the correct measurement is ______.
Answer:
(48.106 ; 53.494)
Step-by-step explanation:
Given the data:
X : 52 48 49 52 53
Sample mean = ΣX / n
n = 5
Sample mean, xbar = 254 / 5 = 50.8
Standard deviation, s = 2.17 (using calculator)
The standard error (SE) : s/√n =2.17/√5 = 0.970
The degree of freedom, df = n-1
df = 5 - 1 = 4
Tscore(0.05, 4) = 2.776
Confidence interval :
Xbar ± Tscore*standard error
50.8 ± (2.776 * 0.970)
50.8 ± 2.694
Lower boundary = 50.8 - 2.694 = 48.106
Upper boundary = 50.8 + 2.694 = 53.494
(48.106 ; 53.494)

Answer:
circumference = 40.82 m
area = 132.67 m²
Step-by-step explanation:
circumference = diameter x π = 13 x 3.14 = 40.82 m
radius = diameter/2 = 13/2 = 6.5
area = πr² = )3.14)(6.5²) = 132.67 m²
This table goes through the pairs(51,-65) and (68,-78).What is the yintercept of the line?
Answer:
I think the y intercept is (0,-26)
Step-by-step explanation:
Answer:
(0, -26)Step-by-step explanation:
Find the slope:
m = (-78 + 65)/(68 - 51) = -13 / 17Use point-slope form to find the equation of the line:
y - (-65) = -13/17(x - 51)y = -13/17x + 39 - 65y = -13/17x - 26The y-intercept is - 26

A cube is labeled 1 - 6 what is the probability that it will land on a number less that 3
Answer:
1/3
Step-by-step explanation:
There are 6 sides on a number cube, and 2 numbers on the cube that are less than 3... 1 and 2. So, 2/6 or 1/3 is the probability that the cube would land on a number less than 3.

solution of f'(x) = 9x2+2x (-2,2)
Answer:
f(x) = 3x³ + x² + 22
Step-by-step explanation:
Given
f'(x) = 9x²+2x
To get f(x), we will be integrating the function
f(x) = 9x³/3 + 2x²/2 + C
f(x) = 3x³ + x² + C
at (-2,2)
2 = 3(-2)³ +(-2)² + C
2 = -24 + 4 + C
2 = -20 + C
C = 2+20
C = 22
Get the required function
f(x) = 3x³ + x² + C
f(x) = 3x³ + x² + 22
In most residence, the largest bedroom is considered the Masters Bedroom. Which bedroom would be considered the Masters Bedroom based on area? * bed room 2 bedroom 1
Answer:
Bedroom 2 will be considered as the Master bedroom.
Step-by-step explanation:
Area of bedroom 1 = Area of room 1 - Area of the closet 1
Area of the room 1 = Length × Width
= (2.5 + 1.4) × (4.3+0.6)
= 3.9 × 4.9
= 19.11 m²
Area of closet 1 = 1.5 × 0.6
= 0.90 m²
Area of bedroom 1 = 19.11 - 0.90
= 18.21 m²
Area of bedroom 2 = Area of room 2 - (Area of bathroom + Area of Hall)
Area of room 2 = (3 + 3.1) × (2.5 + 2.4)
= 6.1 × 4.9
= 29.89 m²
Area of bathroom = 3 × 2.5
= 7.5 m²
Area of Hall = 1.2 × 2.4
= 2.88 m²
Area of bedroom 2 = 29.89 - (7.5 + 2.88)
= 29.89 - 10.38
= 19.51 m²
Since, area of bedroom 2 is greater than bedroom 1.
Therefore, Bedroom 2 will be considered as the Master bedroom.

Write and solve a word problem for the expression
Answer:
9 pizzas total were bought for a party. Maya ate 1/3 of a pizza. John ate 4/9 of the same pizza. How much pizza is left?
Answer: 74/9 or 8.2
Step-by-step explanation:
first add 4/9 and 1/3 since it's in parenthesis
4/9+1/3
they need to have the same denominator, use the LCM (which is 9)
multiply 1/3 by 3 to achieve the LCM
4/9+3/9
add together numerators
7/9
subtract 7/9 from 9
9/1-7/9
get 9 to achieve the LCM (which is 9 again)
multiply 9/1 by 9
81/9 minus 7/9= 74/9

PEMDAS. VERY IMPORTANT. THIS ACRONYM WILL HELP YOU WHEN SOLVING MULTI-STEP PROBLEMS. IF YOU DO NOT KNOW IT, SEARCH IT UP. I'LL BE USING PART OF THIS ACRONYM TO SOLVE THIS PROBLEM.
First you solve things in paratheses:
1. (14 ÷ 2) x 5 + 6 -> (7) x 5 + 6
2. {3 x (4 + 1)} ÷ 5 -> {3 x 5} ÷ 5 -> 15 ÷ 5
Then, you multiply or divide next:
1. (7) x 5 + 6 -> 35 + 6
2. 15 ÷ 5 = 3
We already have the answer to number 2, but not number one, so we will keep going. Finally, you subtract or add:
1. 35 + 6 = 41
Now you have your answers. Hope this helps!

Sisters Sharon and Karen enjoy sleeping. Let X represent the number of hours Sharon sleeps each night, and let Y represent the number of hours Karen sleeps each night. The mean of X is 7.9, and the mean of Y is 8.4. Which answer choice correctly calculates and interprets the mean of the sum, S = X + Y?
Mu Subscript s Baseline = 0.5; the mean amount of sleep Sharon and Karen get is 0.5 hours nightly.
Mu Subscript s Baseline = 8.15; the mean amount of sleep Sharon and Karen get is 8.15 hours nightly.
Mu Subscript s Baseline = 8.15; Sharon and Karen can expect to sleep a total of 8.15 hours, on average, nightly.
Mu Subscript s Baseline = 16.3; Sharon and Karen can expect to sleep a total of 16.3 hours, on average, nightly.
Answer: D
Step-by-step explanation: right on edge :)
[tex]\mu_S[/tex] = 8.15, the mean hours of sleep Sharon and Karen get is 8.15 hours nightly.
What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
Given, Two persons 'X' and 'Y' has mean sleeping hours of 7.9 and 8.4.
Therefore, The mean sleeping hours of both combined is (X + Y)/2 which is,
= (7.9 + 8.4)/2.
= 16.3/2.
= 8.15 hours.

Answer:
D
Step-by-step explanation:
The graph covers two different conditions which is identified by the red line :
The first red line starts from - 3 and arrows to the left this represents the condition x < - 3 ; because of the movement to the left.
The Second redline starts from 1, with the starting point shaded then arrow points to the right of the number line this represents two conditions (rightward direction means greater Than, shaded starting point means =) Hence the condition is ≥ 1
