According to a patient advocacyorganization, the mean expense for a seriously ill patient admitted for a seven-day-stay at Golden Grove General Hospital is $24,000, without insurance or other reimbursements.These champions of consumers are concerned that the mean average expense has increased recently.They took a random sample of 16 such patient stays, and found that the mean average expense, before insurance is $31,500.The lowest recorded expense in the sample is $5,000; the highest is $65,000.Test, at the 5% level of significance, the patient advocates' suspicion that the population mean average expense has risen.[COMMENTS & HINTS:Clearly state the hypotheses and the conclusion.The distribution cannot be presumed normal; instead, apply the sampling distribution.Which test statistic,torz, is appropriate?Is it a one-tail or two-tail test?
