IASSC ICBB Exam - Topic 1 Question 63 Discussion

What conclusion is most correct about the Experimental Design shown here with the response in the far right column?
C) If the Adv is increased from the low level to the high level, the response rate increases
A) No factor has enough statistical confidence greater than 95% to have an impact on the response rate
B) Constant, Adv and Bev are the only factors statistically affecting the response rate with 95% confidence or more
D) The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate
E) This design does not have enough experimental runs to conclude anything as evidenced by the lack of P-values in the MINITABTM output

B is interesting, but I don’t see how they can be the only ones affecting it.

I vaguely remember that if there aren't enough experimental runs, we can't draw strong conclusions. So, option E might be a valid point to consider.

I'm a bit uncertain about whether the response rate really increases with Adv. It seems logical, but I need to double-check the data from our practice problems.

I think I saw a similar question where we had to identify which factors were significant. I feel like Adv and Bev might be the key ones here, but I can't recall the exact details.

I remember we discussed how a 95% confidence level is crucial for determining significance, but I'm not sure if all factors meet that threshold here.

Hmm, this is a tricky one. I'm not entirely sure how to interpret the lack of p-values in the output. I may need to make some assumptions or inferences to arrive at the best conclusion.

Based on the information provided, I think option B is the most correct. The output shows that Constant, Adv, and Bev are the only factors with effects greater than 95% confidence.

I'm a bit confused by the lack of p-values in the output. Without those, it's going to be tough to determine statistical significance. I'll need to double-check the experimental design to see if there are any clues there.

Okay, let me think this through step-by-step. The question is asking about the conclusions we can draw from the experimental design, so I'll need to focus on interpreting the results shown in the output.

Hmm, this looks like a tricky one. I'll need to carefully review the MINITAB output and the experimental design to determine which factors are statistically significant.

I've seen this type of question before. I think the best approach is to start by creating the storage account, and then work on the managed identity piece. That should get me on the right track.

Ah, I remember learning about this in class. Ultrasonic humidifiers use high-frequency vibrations to turn water into a fine mist. That's the key feature that sets them apart from the other types. I'm confident that's the right answer.

Okay, if I recall right, ROI is net profit divided by investment cost. But I can't shake off the feeling that "10%" is too low given the context.

Wow, this experiment must have been sponsored by the 'Ministry of Silly Designs'! I hope they have a backup plan for when the results turn out to be a total mess.

Haha, this design is a real head-scratcher! I guess the experimenters got a little carried away with the 'high' and 'low' levels. E seems like the safest bet here.

I'm not sure about this one. The design seems a bit incomplete, but I would go with D. Minimizing the factors seems like the best way to get the largest response.
