Transcribed Image Text:A new baker is trying to decide if he has an appropriate price set for his 3 tier wedding cakes which he sells
for $93.32. He is particullarly interested in seeing if his wedding cakes sell for more than the average
price. He searches online and finds 23 of the competitors in his area that sell 3 tier wedding cakes with a
mean price of $86.87 with a standard deviation of $10.11. Help the new baker by testing his his claim with
a 0.10 level of significance.
The correct hypotheses would be:
Ο Η0: μ < $93.32
HA: µ > $93.32 (claim)
O Ho: µ > $93.32
HA: µ < $93.32 (claim)
Ο H: μ = $93.32
HA:µ + $93.32 (claim)
Since the level of significance is 0.10 the critical value is -1.321
The test statistic is:
(round to 3 places)
The p-value is:
(round to 3 places)
The decision can be made to:
O reject Ho
O do not reject Ho
The final conclusion is that:
O There is enough evidence to reject the claim that his wedding cakes sell for more than the average
price.
O There is not enough evidence to reject the claim that his wedding cakes sell for more than the
average price.
O There is enough evidence to support the claim that his wedding cakes sell for more than the average
price.
O There is not enough evidence to support the claim that his wedding cakes sell for more than the
average price.
