<PRE><B>Question 145278</B>
I am having trouble trying to figure out how to work this probability problem. Could anyone please help me with these? Thank you so much!
A local retail outlet found that 64 out of a sample 133 customers purchased more than $50 in merchandise in a single trip.  
a. Find the probability a randomly selected customer spent more than $50 in a single trip.  (Round your answer to 3 decimal places.)
&lt;pre&gt;&lt;font size = 4 color=&quot;indigo&quot;&gt;&lt;b&gt;
We assume 

{{{probability_that_a_customer_spends_more_than_50_dollars = 64/133 = .481}}}
&lt;/pre&gt;&lt;/font&gt;&lt;/b&gt;
b. Determine whether the probability of error found in #5 is empirical or theoretical probability.  
&lt;pre&gt;&lt;font size = 4 color=&quot;indigo&quot;&gt;&lt;b&gt;
{{{Empirical}}}
&lt;/pre&gt;&lt;/font&gt;&lt;/b&gt;
c. Based on these sample values, how many customers out of 2500 would be expected to spend more than $50 in a single trip?  Give your answer to the nearest whole number.
&lt;pre&gt;&lt;font size = 4 color=&quot;indigo&quot;&gt;&lt;b&gt;
{{{Expectation = (2500)(.481) = 1203}}}

Edwin&lt;/pre&gt;</PRE>
