1. State the appropriate null and alternate hypotheses.
2. Compute the P-value.
Complete question :
Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.
1. State the appropriate null and alternate hypotheses.
2. Compute the P-value.
Answer:
H0 : p = 0.5
H1 : p < 0.5
P value = 0.200454
Step-by-step explanation:
Given that :
Claim : Less than half internet users have posted photos or videos online.
Sample Proportion (p) = 865 / 1765 = 0.4900
The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.
The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;
P = 0.5
q = 1 - 0.5 = 0.5
The test statistic :
Z = p - p0 / sqrt(p0 * (q/n))
Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))
Z = - 0.01 / sqrt(0.5 *0.0002832)
Z = - 0.01 / sqrt(0.0001416)
Z = - 0.01 / 0.0119013
Z = - 0.8402443
The corresponding p value from the z statistic score at α = 0.01
= 0.200454
List the sides in order from shortest to longest. The diagram is not to scale.

your 3 math answer scores are 75,98 and 91 what is your average score
Answer:
88
Step-by-step explanation:
It is given that,
Three scores are 75,98 and 91.
We need to find average score.
The formula to find the average is given by :
[tex]\text{Average}=\dfrac{\text{sum of observations}}{\text{total no of observations}}[/tex]
Using the above formula,
[tex]A=\dfrac{75+98+91}{3}\\\\=88[/tex]
Hence, my average score is 88.
Tom, Lisa, and Jane are competing in a cooking competition. They all used different amounts of sugar from a can containing 4 pounds of sugar.
• Tom used 13% of the total sugar in the can.
• Lisa used 0.6 pound of the total sugar in the can.
• Jane used 0.12 of the total sugar in the can.
Who used the greatest amount of sugar from the can? Show your work and explain your answer in words.
Step-by-step explanation:
Tom used: 0.52 I figured it out by doing this: 0.13x4= 0.52
Lisa used: 2.4 I figured it out by doing this: 0.6x4= 2.4
Jane used: 0.48 I figured it out by doing this: 0.12x4= 0.48
so Lisa used the most
hope it helps!
Answer: Lisa used the most

Answer: b
Step-by-step explanation:
Cuz is a negative get in absolute value it always comes out positive
And it says below 0-9=-9
Answer:
BStep-by-step explanation:
__________________________________________________________
B is the answer because,
if the negative sign is not inside the "brackets," then the number will still be negative.
__________________________________________________________
But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.
__________________________________________________________
Here are the reasons why the rest are wrong.
__________________________________________________________
A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.
__________________________________________________________
C is not correct because it is plainly not correct in itself.
__________________________________________________________
D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

At a large university, 434 freshmen, 883 sophomores, and 43 juniors are enrolled in an introductory algorithms course. How many sections of this course need to be scheduled to accommodate all these students if each section contains 34 students?
Answer: it will take 40 sections the course to accommodate all the students
Step-by-step explanation:
Given that;
434 freshmen, 883 sophomores and 43 juniors are enrolled
total number of students enrolled = (434 + 883 + 43) = 1360
number of student in one section = 34
now
number of sections of an introductory algorithms course needed to be scheduled to accommodate all these students will be;
Total number of section = total number of students enrolled / number of student in one section
so we substitute
Total number of section = 1360 / 34
Total number of section = 40
Therefore it will take 40 sections the course to accommodate all the students

Step-by-step explanation:
if 4/3 x 3/4 = 5k, then k = ?
Answer:
k= 1 /15 x^3
Step-by-step explanation:
4/3 x 3/4 = 5k
5k= 1 /3 x^3
k= 1 /15 x^3
The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.
To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.
Multiplying the fractions on the left side:
(4/3) × (3/4) = 12/12 = 1
Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.
Dividing both sides of the equation by 5:
1/5 = k
Hence, the value of k in the given equation is 1/5.

The correct question is as follows:
If (4/3) × (3/4) = 5k, then find the value of k.

Betty tabulated the miles-per-gallon values for her car as 26.5, 28, 30.2, 29.6, 32.3, and 24.7. The sample standard deviation is 2.728. The driver’s manual for Betty’s car lists the mpg for her car as 25. t equals fraction numerator x with bar on top minus mu over denominator begin display style beveled fraction numerator s over denominator square root of n end fraction end style end fraction The t test statistic for a two-sided test would be __________.
Answer:
3.188
Step-by-step explanation:
Given that :
Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7
Sample standard deviation (s) = 2.728
Mean (mu) = 25
Tstatistic formula :
(x - mu) / (s/sqrt(n))
n = sample size = 6 ; s = 2.728 ; mu = 25
Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6
Sample mean (x) = 171.3 / 6 = 28.55
Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))
Tstatistic = 3.55 / 1.1137013
Tstatistic = 3.1875692
