Here's a problem I'm stuck with:
A survey for brand recognition is done and it is determined that 70% of consumers have heard of Mike's Mechanic Shop. A survey of 900 randomly selected cosumers is to be conducted. For such groups of 900, would it be unusual to get 527 consumers who recognized this shop? So I have to show all the statistics.....
So I'm not clear whether I divide 527/900? Or do I multiply (900)*(.70)?
And why would it be unusual? Do I have to draw a bell shaped curve as well (what would it look like)?
I need this explained step by step.
