Reputation usually affects buying decisions, so -0.7 makes sense.

I’m a bit confused about how to interpret the rankings. Did we cover how to handle ties in Spearman's calculations?

I feel like -0.9 could be the answer since a strong negative correlation seems likely given the context, but I need to double-check my calculations.

I think we did a similar question in class where we calculated correlation coefficients. I might lean towards -0.8, but I’m not entirely confident.

Okay, so the question is asking why desirability is the starting point for a successful idea. I'm guessing the answer has to do with focusing on the customer's needs and wants, rather than just building something and hoping people will want it.

I think the key here is to keep the housekeeping team satisfied, since they'll be the ones wearing the uniforms. They have a high interest in this, so we need to make sure they're happy with the final product.

I think I remember that most shell company schemes do indeed focus on goods, but I'm not completely sure if that's always the case.
