3. What methods are you using to test this (or each) hypothesis?.

Traditional Method->>>>I'm not 100% sure of my answer but gl buddy

Step 1 Identify the Null Hypothesis and the Alternative Hypothesis

Step 2 Identify α (Level of Significance)

Step 3 Find the critical value(s)

Step 4 Find the test statistic

 For a Proportion: Hand calculation

TI 83/84 – Use 1PropZTest (See Handout H-404)

 For a population mean (with α known):

TI 83/84 - Use Z-Test (See Handout H 404)

 For a population mean (with α Not known):

TI 83/84 - Use T-Test (See Handout H-404)

Step 5 Draw a graph and label the test statistic and critical value(s)

Step 6 Make a decision to reject or fail to reject the null hypothesis

 Reject - The test statistic falls within the critical region.

 Fail to Reject - Test statistic does not fall within the critical

region.

P-Value Method:

P-value is the area determined as follows:

 Left Tail Test: p-value is the area to the left of the test statistic.

 Right Tail Test: p-value is the area to the right of the test statistic.

 Two Tailed Test: p-value is twice the area bounded by the test statistic

Make a decision to reject or fail to reject the null hypothesis:

 Reject if p-value ≤ α

 Fail to reject if p-value > α

Hope this help! :)

the results is a decrease in air temperature with an increase of altitude.
