Answers
Answer:
<1 = 138degrees
<2 = 156degrees
Step-by-step explanation:
From the diagram given;
angle at the vertex = 36degrees
Angle at the intercepted arc are <1 and 66degrees
Using the theorem;
Angle at the vertex is 1/2 the difference of the angles at the intercepted arcs
36 = 1/2(<1-66)
36*2 = <1-66
72 = <1 - 66
<1 = 72+66
<1 = 138degrees
Also since the sum of angle in a circle is 360degrees, hence;
<1 + <2 + 66 = 360
138 + <2 + 66 = 360
<2 + 204 = 360
<2 = 360 - 204
<2 = 156degrees

A statewide real estate sales agency, Farm Associates, specializes in selling farm property in the state of Nebraska. Its records indicate that the mean selling time of farm property is 90 days. Because of recent drought conditions, the agency believes that the mean selling time is now greater than 90 days. A statewide survey of 100 farms sold recently revealed that the mean selling time was 94 days, with a standard deviation of 22 days.
Required:
At the 0.10 significance level, has there been an increase in selling time?
Answers
Answer:
The right answer is "1.818".
Step-by-step explanation:
The given values are:
a = 0.1
[tex]\bar{x} = 94[/tex]
[tex]\mu = 90[/tex]
Now,
The test statistic will be:
⇒ [tex]t=\frac{\bar{x}-\mu}{\frac{s}{vn} }[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{94-90}{\frac{22}{10} }[/tex]
⇒ [tex]=\frac{4}{2.2}[/tex]
⇒ [tex]=1.818[/tex]

Step-by-step explanation:
An insurance company classifies drivers as low risk, medium risk, high risk. Of those insured, 60% are low-risk, 30% are medium-risk, and 10% are high risk. After a study, the company finds that during a1-year period, 1% of the low risk drivers had an accident, 5% of the medium risk drivers had an accident, and 9% of the high-risk drivers had an accident.
Required:
a. If a driver had an accident during the year, find the probability that the driver is selected as a medium-risk driver.
b. If a driver who had an accident during the I-year period is selected, what is the probability that he has been classified as high-risk?
c. If two drivers who had an accident during the I -year period are selected, what is the probability that at least one of them has been classified as high-risk?
Answers
Answer:
a. 0.5 = 50% probability that the driver is selected as a medium-risk driver.
b. 0.3 = 30% probability that he has been classified as high-risk
c. 0.51 = 51% probability that at least one of them has been classified as high-risk.
Step-by-step explanation:
To solve this question, we need to understand conditional probability, for items a and b, and the binomial distribution, for item c.
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
a. If a driver had an accident during the year, find the probability that the driver is selected as a medium-risk driver.
Event A: Had an accident
Event B: Medium-risk driver
Probability of having an accident:
0.01 of 0.6(low risk)
0.05 of 0.3(medium risk)
0.09 of 0.1(high risk)
So
[tex]P(A) = 0.01*0.6 + 0.05*0.3 + 0.09*0.1 = 0.03[/tex]
Probability of having an accident and being a medium risk driver:
0.05 of 0.3. So
[tex]P(A \cap B) = 0.05*0.3 = 0.015[/tex]
Desired probability:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.015}{0.03} = 0.5[/tex]
0.5 = 50% probability that the driver is selected as a medium-risk driver.
b. If a driver who had an accident during the I-year period is selected, what is the probability that he has been classified as high-risk?
Event A: Had an accident
Event B: High risk driver.
From the previous item, we already know that P(A) = 0.03.
Probability of having an accident and being a high risk driver is 0.09 of 0.1. So
[tex]P(A \cap B) = 0.1*0.09 = 0.009[/tex]
The probability is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.009}{0.03} = 0.3[/tex]
0.3 = 30% probability that he has been classified as high-risk
c. If two drivers who had an accident during the I -year period are selected, what is the probability that at least one of them has been classified as high-risk?
0.3 are classified as high risk, which means that [tex]p = 0.3[/tex]
Two accidents mean that [tex]n = 2[/tex]
This probability is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{2,0}.(0.3)^{0}.(0.7)^{2} = 0.49[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.49 = 0.51[/tex]
0.51 = 51% probability that at least one of them has been classified as high-risk.
