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

I found some possible answers:
A. “what do you think these cookies?”
B. “What is your opinion of these cookies?”
C. “How do you feel about these cookies?”
D. “How do you like these delicious cookies?”
Option D is the correct answer because the word "delicious" could effect the person's answer to benefit the cookies.
a and b represent the slopes in the equations. Use the y-mx+b formula to realize this. M is the slope, a or b in this question. The lines both have positive slopes so B or C cannot be the answer. I cant see the image properly, but if the y int is at 0 then A is the answer, but if it is above 0 then D will be your answer.
The answer fam is......... D)
