Scholars and different analysts expounding on likelihood have quarreled over how to best decipher the numerical contraption. Here are three wide perspectives about how to decipher likelihood claims. To start with, we may take likelihood professes to be claims about the recurrence of some occasion in a grouping of occasions. For instance, on the off chance that I flip a coin multiple times and "Heads" comes up multiple times, I may say that the likelihood of "Heads" in that arrangement of flips is 53 out of 100; the recurrence with which the occasion "Heads comes up" happens in the grouping of flips. Second, we may take likelihood professes to be claims about how much we accept that some sentence is valid. For instance, in the event that I am pondering wagering on the following flip of the coin, I may accept that "Heads" will come up more emphatically than I accept that "Tails" will come up. Third, we may take likelihood professes to be claims about how much our proof backings a sentence. For instance, we may realize that at any rate one of three coin flips is "Heads" and ask how much help that provides for the case that every one of the three coin flips are "Heads."

Answer the accompanying inquiries.

a) select an understanding of likelihood from the brief above to safeguard.

b) Give purposes behind choosing/underwriting the translation you chose.

c) Give purposes behind dismissing the understandings you didn't choose.

A specialist leads a various relapse investigation with two-followed ? = .05. They foresee thermometer appraisals for Trump during the 2016 political decision (0 to 100) from two different factors. One is whether individuals concur with the assertion "social sensitivity has gone excessively far" (- 3 = emphatically dissent, 0 = neither concur or deviate, 3 = firmly concur). The other is whether individuals concur with the assertion "the US enjoys been taken benefit of in terms of professional career manages different nations" (same scale). The coefficient for apparent sensitivity is 11.5 and p = .03. The coefficient for exchange is 2.1 and p = .09. What is the scientist's considerable decision?

A)

Both review social sensitivity and exchange as an issue anticipated more prominent help for Trump

B)

Survey wokeness as an issue anticipated more prominent help for Trump, however exchange sees didn't foresee support

C)

Survey exchange as an issue anticipated more noteworthy help for Trump, yet overt sensitivity didn't foresee support

D)

is not compatible with Trump's variable

prediction. A researcher is studying whether the rain will depress voting. They compared the percentage of registered voters in areas with rain (34%) and areas without rain (45%). They used an independent sample t-test and rejected the null hypothesis. What are your substantive conclusions?

A)

Less electors turned out in places with downpour

B)

More electors turned out in places with downpour

C)

The quantity of electors turned out in places with and without downpour

D)

Can't decide from data given

A specialist needs to know whether the quantity of hours individuals spend watching satellite TV news is identified with their doubt of government (estimated 0 = don't confide in every one of the, 100 = trust definitely). Which technique will they use to test this thought?

''2''

A)

One-example t-test

B)

Relationship

C)

Straight Regression

D)

BOTH Correlation and Linear Regression would be suitable

4. A parallel system consists of 3 components A, B, and C. If the reliabilities of three components are RA = 0.9 Ra=0.8 and R.=0.7, find the system reliability. If the components follow exponential probability density function for failures with average failure rate, 0.001 failure/hour, what is the MTBF for the system? ( 25 points)Question 4: (8 mark) Consider a system built with two series components I and 2. The reliability of each component is RI=0.9 and R2= 0.81. R2 RS R1 1-Calculate the system reliability. To improve the reliability of the system, 2 identical modules identical to component 2 has been added in parallel with the critical part as shown in the figure. RS1 R1 R2 R12 R22 2-Give the overall system reliability Rs, and compare it to R.7. Components A1, A2 are identical with reliability at 10,000 hours of 0.8. Components B1 and B2 are identical with reliability at 10,000 hours of 0.9. Components C1, C2 and C3 have reliability at 10,000 hours of 0.7 each. Component D has reliability at 10,000 hours of 0.75. A1 D a. Calculate the reliability at 10,000 hours of the system. (10 points) b. What would you recommend to further improve the reliability of this system? (5 points) 94. The term reliability refers to the probability that a device does not fail. Suppose a mechanical system consists of three components that function independently. It is known that component 1 has a reliability of .98, component 2 has a reliability of 95, and component 3 has a reliability of 0.99. If the system can function if at least one component functions, what is the reliability of the system? 5. The term reliability refers to the probability that a device does not fail. Suppose a mechanical system consists of three components that function independently. It is known that component 1 has a reliability of .98, component 2 has a reliability of 95, and component 3 has a reliability of 0.99. Suppose now you develop an alternative system with two identical components, each of which has the same reliability p. This system functions only if all components function. What is the minimum p needed to make sure this machine has a reliability greater than or equal to 0.95? 6. There are 25 pens in a drawer in your desk. Among them, 20 write well and 5 are defective. You will randomly select 4 pens to give to your classmate. Your classmate randomly selects one of the four pens that she received from you. Calculate the probability the pen she chose writes well.
