The average age of a breed of dog is 19.5 years. if the distribution of their ages is normal and 20% of dogs are older than 22.6
viva [34]

The  standard deviation of the average age of a breed of dog  is said to be 3.69.

<h3>What is the standard deviation about?</h3>

Note that we take:

  • x = dog age has mean 19.5
  • Unknown standard deviation.

Hence:

z = (x - mean) /SD is distributed N (0,1) - mean o standard deviation 1 (standard normal)

Since 20% of dogs are known to be older than 22.6 years:

So 22.6 years is said to be 80th percentile,

Since z matching to 80th percentile (using the standard normal table) s is <em>0.84.</em>

Then one need to plug z, x which is  = 22.6

mean = 19.5 into the stated z equation:

Hence,

0.84 = (22.6 - 19.5)/SD

SD = (22.6 - 19.5)/0.84

= 3.69

What is the slope of this graph?<br> (1.6)<br> 13.0)<br> The slope of the graph is
Maurinko [17]
I suppose you are saying that your points are (1,6) and (13,0), correct?

If so, to find slope use this equation:
(Y2 - Y1)/(X2 - X1)

Let’s input the missing values:
(0 - 6)/(13 - 1)

You should get:
-6/12

(Optional but reccomended) Simplify:
-1/2
