Null Hypothesis claims that average price for gas is equal 3

Null Hypothesis claims that average price for gas is equal $3.67/gal, Ho: = 3.67

Alternative hypothesis claims that average price for gas is greater than $3.67/gal, H_A: > 3.67 .

Classify this hypothesis test as two-tailed, left-tailed or right-tailed.

Two-Tailed test

Left-Tailed test

Right-Tailed test

Solution

If it uses =/=, it is two tailed.

For >, right tailed.

For <, left tailed.

hence, here, Ha: u > 3.67.

hence, it is RIGHT TAILED. [ANSWER]
