Go to the negative part of the graph go to 6x the 8x and draw lines connecting the 2 then do an = and put -24
Step-by-step explanation:
We define 3 events
A = event that driver is above speed limit
B = event that driver is below limit
T = event that the gun detected him
At 95%
P(A) = 1-0.95 = 0.05
P(B) = 0.95
P(T|A) = 0.98
P(A|T) = 0.02
P(T|B) = 1-0.99 = 0.01
P(B|T) = 0.99
1. For answer a
P(TnA) = P(A) x P(T|A)
= 0.05 x 0.98
= 0.049 is the probability gun detected speeding and the driver was speeding
2. For answer b
P(TnB) = P(B) x P(T|B)
= 0.95x0.01
= 0.0095 is probability that gun deects speeding and driver was not speeding
3. For answer c
We solve this using bayes theorem
P(B|T) = P(B) x P(T|B) / (P(B)*P(T|B)) + (P(A) +P(T|A))
= 0.095x0.01 divided by (0.95x0.01)+(0.05*0.98)
= 0.0095 divided by 0.0585
= 0.16239
= 0.1624 to 4 decimal places.
It is known as Statistical Inference.
Statistical Inference
- Without sampling and statistical estimation of the value, some population parameters cannot ever be known. Take customer preference samples, for instance. Since asking everyone would be impractical, choose a sample to identify the parameter.
- A population's mean can be estimated quite well using the confidence interval. It offers a spectrum of values that most likely includes the population mean. The interval gets smaller as sample size increases.
- The method of ordinary least squares is used in a regression equation to develop an equation that best fits the data of an independent variable and dependent variable.
