Answer:

Step-by-step explanation:

Yes, this distance will be different depends on the car, exactly the car's motor, we could have the same gasoline litter but if we have a car with a small motor the gasoline would last longer.

For example:

A small car could travel more miles than a big car with a v6 motor, a small car could use 4 litter in an hour, in a truck could use 8 litter or more in an hour depends on the motor, assuming we traveled 24.2 miles per hour.

A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard devia

WITCHER [35]

Answer:

Upper P60 = 212.8

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 200, \sigma = 50$
