The number of "destination weddings" has skyrocketed in recent years. For example, many couples are opting to have their weddings in the Caribbean. A Caribbean vacation resort recently advertised in Bride Magazine that the cost of a Caribbean wedding was less than $30,000. Listed below is a total cost in $000 for a sample of 8 Caribbean weddings. At the 0.10 significance level, is it reasonable to conclude the mean wedding cost is less than $30,000 as advertised?

0.10 level of significance. (Enter your answers in thousands of
dollars.)
State the decision rule for 0.10 significance level. (Negative
amount should be indicated by a minus sign. Round your answer to 3
decimal places.)
Compute the value of the test statistic. (Negative amount should
be indicated by a minus sign. Round your answer to 3 decimal
places.)
What is the conclusion regarding the null hypothesis?
