When I use geogebra to draw the box plot, I get what you see in the attached image.
It's hard to say for sure since there are no numbers assigned to any of the boxplots, but it looks like
the answer is choice D. This is due to these things I've noticed
A) The median is closer to Q3 than it is to Q1
B) Q1 is very close to the min compared to the distance from Q3 to the max
Answer:
C
Step-by-step explanation:
So if it's not 180°, it won't be a triangle :)
Hope this helps!
Answer: 0.9147
Step-by-step explanation:
Given: 20% of the plants ordered are petunias.
Let p = 20% = 0.2
Sample size: n = 120
If they follow normal distribution, then mean = np = 120x 0.2 = 24
Standard deviation = ![\sqrt{n p(1-p)}=\sqrt{120\times0.2\times.8}](https://tex.z-dn.net/?f=%5Csqrt%7Bn%20p%281-p%29%7D%3D%5Csqrt%7B120%5Ctimes0.2%5Ctimes.8%7D)
![=\sqrt{19.2}\\\\ =4.38](https://tex.z-dn.net/?f=%3D%5Csqrt%7B19.2%7D%5C%5C%5C%5C%20%3D4.38)
The probability that no more than 30 plants are petunias : ![P(\dfrac{X-\mu}{\sigma}\leq \dfrac{30-24}{4.38})](https://tex.z-dn.net/?f=P%28%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%5Cleq%20%5Cdfrac%7B30-24%7D%7B4.38%7D%29)
![=P(Z](https://tex.z-dn.net/?f=%3DP%28Z%3C1.37%29%3D%200.9147)
Hence, the probability that no more than 30 plants are petunias = 0.9147
