ative frequencies
1 answer:
Answer:
Probability of having broken glass = 0.1933
Probability of not having broken glass = 0.8067
Step-by-step explanation:
The Treatment table in the file attached to the given question is written out and completed below;
Treatment
Response Smashed into Hit Control Total
Yes 16 7 6 29
No 34 43 44 121
Total: 50 50 50 150
Using relative frequencies,
the distribution of responses about whether there was broken glass at the accident for the subjects in this study can be computed as follows:
Probability of having broken glass =
Probability of having broken glass = 0.1933
Probability of not having broken glass =
Probability of not having broken glass = 0.8067

Answer:
0.5488 = 54.88% probability that there are no defects in the completed highway.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
The portion of highway that your city is building is 30 miles long.
The mean is one defect per 50 miles. Since the highway is 30 miles, we have that:
What is the probability that there are no (0) defects in the completed highway?
This is P(X = 0). So
0.5488 = 54.88% probability that there are no defects in the completed highway.
