Yoonie is a personnel manager in a large corporation. Each month she must review 16 of the employees. From past experience, she has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. Let X be the random variable representing the time it takes her to complete one review. Assume X is normally distributed. Let X be the random variable representing the mean time to complete the 16 reviews. Assume that the 16 reviews represent a random set of reviews.

Find the probability that the mean of a month's reviews will take Yoonie from 3.5 to 4.25 hrs.

a. Give the probability statement and the probability. (Enter exact numbers as integers, fractions, or decimals for the probability statement. Round the probability to four decimal places.

Answer:

The slope is [tex]-3[/tex], and the y-intercept is [tex]2[/tex].

Explanation:

Step 1: Recognize the slope-intercept form

The slope-intercept form of an equation is:

[tex]y=mx+b[/tex]

Where [tex]m[/tex] represents the slope, and [tex]b[/tex] represents the y-intercept.

Step 2: Arrange the equation into the slope-intercept form

The equation is given as:

[tex]9x+3y=6[/tex]
First of all, let's make [tex]3y[/tex] the subject:

[tex]9x+3y=6\\\\\text{Subtract 9x from both sides:}\\9x+3y-9x=6-9x\\\\\text{Simplify:}\\3y=-9x+6[/tex]

Now, let's make [tex]y[/tex] the subject:

[tex]3y=-9x+6\\\\\text{Divide by 3 on both sides of the equation:}\\\frac{3y}{3}=\frac{-9x}{3}+\frac{6}{3}\\\\\text{Simplify}:\\y=-3x+2[/tex]

Step 3: Identify the slope and y-intercept

The slope-intercept form of the equation is:

[tex]y=-3x+2[/tex]

And the slope-intercept form is:

[tex]y=mx+b[/tex]

So, [tex]m=-3[/tex] and [tex]b=2[/tex].

This means that the slope is [tex]-3[/tex], and the y-intercept is [tex]2[/tex].
