Answer:
RDS.
Explanation:
A corporation has implemented a software that conducts the number of information overwriting and deleting, which allows the newest details to be accessible whenever the information is examined. As a Software Engineer, they suggest RDS database technologies.
It is an AWS supported controlled SQL DB service that also reinforces the array type DB for the purpose to contain and maintain the information.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) =
=
= 0.0316
For x = 120, sample proportion(p) =
=
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z <
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
