Question
![A used car dealer says that the mean price of a three-year-old sports utility vehicle is $21,000. You suspect this claim is incorrect and find that a random sample of 21 similar
vehicles has a mean price of $21,696 and a standard deviation of $1956. Is there enough evidence to reject the claim at a= 0.05? Complete parts (a) through (e) below. Assume
the population is normally distributed.
(a) Write the claim mathematically and identify Ho and Ha
Which of the following correctly states Ho and Ha?
O A. Ho: u#$21,000
O B. Ho: u=$21,000
Ha µ= $21,000
O C. Ho: µ2 $21,000
Ha: µ< $21,000
Ha µ<$21,000
O D. Ho: u= $21,000
H u> $21,000
O E. Ho: µ> $21,000
Ha us$21,000
F. Ho: u=$21,000
H2 u#$21,000
(b) Find the critical value(s) and identify the rejection region(s).
What is(are) the critical value(s), to?
to =D
