Category > Statistics Posted 04 May 2017 My Price 5.00

A student organization uses the proceeds

10.92 A student organization uses the proceeds from a particular soft-drink dispensing machine to finance its ac- tivities. The price per can had been $0.75 for a long time, and the average daily revenue during that period had been

$75.00. The price was recently increased to $1.00 per can. A random sample of n = 20 days after the price increase yielded a sample average daily revenue and sample stan- dard deviation of $70.00 and $4.20, respectively. Does this information suggest that the true average daily reve- nue has decreased from its value before the price in- crease? Test the appropriate hypotheses using a = .05.
