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

Answer: y = - 0.4 x - 4.5
Step-by-step explanation:
Equation y=mx+b
m is the slope
x is *ANY* x coordinate
y is *ANY* y coordinate
b is y intercept or WHERE the point is on the Y AXIS
Lets look at the given:
Slope (m) is -2/5
Passes through point 15, -9/2
As you can see, the point goes through the Y axis at (-9/2)
Our equation is y = - 0.4 x - 4.5

your 3 math answer scores are 75,98 and 91 what is your average score
Answers
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.

Answers
Answer:
k=3
Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
step 1: simplify both sides of the equation
([tex]\frac{1}{3}[/tex]) (9k) + ([tex]\frac{1}{3}[/tex]) (3) = (-2) (k) + (-2) (-8) (distribute)
3k + 1 = -2k +16
step 2: add 2k to both sides
3k + 1 + 2k =-2k + 16 + 2k
5k + 1 = 16
step 3: subtract 1 from both sides
5k + 1 - 1 = 16 - 1
5k = 15
step 4: divide both sides by 5
[tex]\frac{5k}{5}[/tex] = [tex]\frac{15}{5}[/tex]
k = 3

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?
Answers
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

Answers
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
