Help on Stating a Null and Alternative Hypothesis

[danny89]

Problem 1
A survey claims that the average cost of a hotel room in Augusta is $73.21. To test the claim, a researcher selected a sample of hotel rooms in Augusta. At α = 0.05, is there enough evidence to reject the claim?

Sample Data:
$79.64 $69.86 $67.25 $71.39 $90.93
$61.45 $74.97 $98.79 $73.23 $94.51
$65.00 $81.30 $94.42 $66.82 $89.11
$77.03 $98.29 $75.84 $69.77 $93.33
$77.85 $92.26 $92.72 $73.03 $85.15
$68.99 $66.06 $74.17 $88.06 $84.58

Step I: State the Null and Alternative Hypothesis


How do you know what this is?

I know this is a multi step problem I just want to make sure I'm heading in the right direction.

Generally, one reads the problem statement.

"the average cost of a hotel room in Augusta is $73.21"

Avg Cost = $73.21

There is one of them. You tell me which one it is and then tell me what the missing one might be.

thanks

thanks I've got the direction I can probably do the rest:

So my hypothesis could be:


The average cost of a hotel in A is equal to the number
then the average cost of a hotel is NOT equal to a number

And it would be a two tailed bc its an equal to problem?
