Answer:
C)30%
Step-by-step explanation:
Prime numbers less than 30 are given below
2,3,5,7,11,13,17,19,23,29
We have to find the probability that sum of three prime numbers selected will be even.
We know that
Sum of any three prime number except 2 will be odd.
Total prime numbers except 2=9
Total prime numbers=10
Probability:P(E)=
Probability of getting sum of three prime numbers selected will be odd=
By using formula
Probability of getting sum of three prime numbers selected will be odd=P(E)=
Probability of getting sum of three prime numbers selected will be odd=P(E)=
Probability of getting sum of three prime numbers selected will be even=P(E')=1-0.7=0.3=%
By using formula P(E')=1-P(E)
Answer:
D) the standard error for her sample is 15
Step-by-step explanation:
Samantha is 95% certain that between 50% and 70% of the first year students agree that they should be able to bring a car to campus.
Here
- 95% is the confidence level.
- The range between 50% and 70% indicates 95% confidence interval.
- 60% is the average proportion of the first year students at her university think they should be able to bring a car to campus.
- 10% (0.1) is the margin of error from the mean
Since standard error can be obtained by dividing margin of error by the z-statistic of the confidence level which is 1.96. The standard error for her sample does not equal to 15.
