Step-by-step explanation:
In a recent school newspaper survey, 3,000 randomly selected teenagers were asked to cite their primary transportation method to school. Fifteen of 20 teenagers said they use their own car to get to school. A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093). Which of the following is a correct interpretation of the confidence level?
Ninety percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who drive their own car to school.
Ninety percent of all samples of this size would yield a confidence interval of (0.5907, 0.9093). (not correct)
There is a 90% chance that the true proportion of teenagers who drive their own car to school will be (0.5907, 0.9093).
Ninety percent of all the samples of size 3,000 lie in the confidence interval (0.5907, 0.9093).
There is a 90% chance that randomly selected teenagers will be part of the 75% who drive their own car to school.
Answer: There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Step-by-step explanation:
Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.
Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).
i.e. A person can be 90% confident that the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).
Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
Answer:
A) Ninety percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who drive their own car to school.

G is the centroid of AABC, FC = 35, AG = 42, BF = 57, and DG = 14. Find BG.
Answer:
[tex] BG = 38 [/tex]
Step-by-step explanation:
Based on centroid theorem of triangles:
[tex] BG = \frac{2}{3} \times BF [/tex]
[tex] BF = 57 [/tex]
Plug in the value into the equation
[tex] BG = \frac{2}{3} \times 57 [/tex]
[tex] BG = \frac{2 \times 57}{3} [/tex]
[tex] BG = \frac{114}{3} [/tex]
[tex] BG = 38 [/tex]
Suppose that fund-raisers at a university call recent graduates to request donations for campus outreach programs. They report the following information for last year's graduates.
Size of donation $0 $10 $25 $50
Proportion of call 0.40 0.30 0.25 0.05
Three attempts were made to contact each graduate. A donation of $0 was recorded both for those who were contacted but who declined to make a donation and for those who were not reached in three attempts. Consider the variable
x = amount
of donation for the population of last year's graduates of this university.
(a) Write a few sentences describing what you think you might see if the value of x was observed for each of 1000 graduates.
You would expect roughly of the graduates to donate nothing, roughly to donate $10, roughly to donate $25, and roughly to donate $50. The frequencies would be close to, but not exactly, these values. The four frequencies would add to .
(b) What is the most common value of x in this population?
$
(c) What is P(x ≥ 25)?
(d) What is P(x > 0)?
Answer:
Following are the solution to the given points:
Step-by-step explanation:
In point a:
It's also expected that approximately [tex]1000 \times 0.40 =400[/tex] of both, the students contribute zero, approximately [tex]1000 \times 0.30 =300[/tex] to donors $10, approximately [tex]1000 \times 0.25 = 250[/tex] donors $25, and then about [tex]1000 \times 0.05 = 500[/tex] dollars $50 donors. Its frequencies would be similar to and not precisely, the probability. The four levels will stack up to a thousand.
In point b:
It is the population, in which the key value of x is a $0 donation ( 40 percent of students do this).
In point c:
[tex]\to P(X \geq 25) \\\\\to 0.25+0.05 \\\\\to 0.30[/tex]
In point d:
[tex]\to P(X>0)\\\\ \to 1-P(X=0)\\\\ \to 1- 0.40\\\\\to 0.60\\\\[/tex]
1.1 Paul leaves from Johannesburg to Limpopo and has to travel 300km to get to his destination: If he travels at a constant speed of 75 km per hour, how many hours will it take him to get there?
1.2 And if he only has 90 minutes to get to his destination, what speed must he travel to get there on time?
Answer:
4 hours ; 200 kmph
Step-by-step explanation:
Given that :
Distance to be covered = 300 km
Speed of travel = 75kmph
Number of hours it will take to get to destination :
Time taken = Distance / speed
Time taken = 300 km / 75 kmph
Time taken = 4 hours
2.) If he has 90 minutes to get to destination, required speed will be ; 90 minutes = 1.5 hours
Speed = distance / time
Speed = 300 km / 1.5 hours
Speed = 200 kmph
