Answer:

Independent.

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

P(A \cap B) = P(A)P(B)

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.

The time required for an automotive center to complete an oil change service on an automobile approximately follows a normal​ di
xxMikexx [17]

Answer:

a) Therefore 92.64% of customers receive the service for​ half-price.

b) Therefore it would take 8.52 minutes

Step-by-step explanation:

Given that ime required for an automotive center to complete an oil change service on an automobile approximately follows a normal​ distribution with:

mean (μ) = 15 minutes

Standard deviation (σ) = 3.5 minutes

a) The z score is given by the equation:

z=\frac{x-\mu}{\sigma}

Since the service will take no longer than 20 minutes,

z=\frac{x-\mu}{\sigma}=\frac{20-15}{3.5} = 1.43

Using the probability table to get the probability of the z score

percent of customers receive the service for​ half-price = P(X < 20) = P(z < 1.43) = 0.9236 = 92.64%

Therefore 92.64% of customers receive the service for​ half-price.

b) Since the probability is 3% = 0.03, this corresponds with a z score of -1.88

Therefore:

z=\frac{x-\mu}{\sigma}=\frac{x-15}{3.5} =-1.88

\frac{x-15}{3.5} =-1.88

{x-15} =-6.58\\x=-6.58+15=8.52\\x=8.52 minutes

Therefore it would take 8.52 minutes
