Answer:

Upper bound for distance = 100.49. This is the highest number that you can round up to get 10.52.

Lower bound for time = 10.515 seconds. This is the lowest number that you can round up to get 10.52.

Upper bound for average speed = Upper bound for distance divided by upper bound for time.

100.49/10.5249 = 9.548 seconds.

Lower bound for average speed = Lower bound for distance divided by lower bound for time.

99.5 / 10.515 = 9.463 seconds.

Complete Question

A recent study found that hourly wages earned by employees possessing a master's degree are distributed normally with a mean of $27.50 and standard deviation of $3.50

At a recent job fair, Intel boasted that they paid master's graduates more than 90% of all

employers. If we interpret their claim as a percentile, what hourly wage must they offer employees with master's degrees?

Answer:

The value is $x = \$31.986$

Step-by-step explanation:

From the question we are told that they paid master's graduates more than 90% of all

Generally from the z-table the z-score for 90% is $z = 1.282$

This z-score can be mathematically represented as

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

Here x is the hourly wage they offer employees with master's degrees

substituting $27.50 for $\mu$ and $3.50 for $\sigma$ we have

$1.282 = \frac{x - 27.50 }{3.50}$

=> $x = \$31.986$
