Question

From 1900 to 2000 the average temperature in July in Atlanta was LaTeX: 90^\circ F90 ∘ F. A researcher believes due to Global Warming that the average temperature is increasing in Atlanta. What could be the null hypothesis?

Answer 1

*100% CORRECT ANSWERS

Answer 2

Answer:
`H_0: \mu=90^(\circ)F`

Explanation:

Definition:

Null hypothesis
`H_0`: It is a statement describing population parameter as per the objective of the study . It generally takes
`=, \leq, \geq` signs.

Alternative hypothesis
`H_1`: It is also a statement describing population parameter as per the objective of the study . It generally takes >, <, ≠ signs.

Let
`\mu` be the average temperature in July in Atlanta.

As per given ,

From 1900 to 2000 the average temperature in July in Atlanta was 90°F.

i.e.
`\mu=90^(\circ)F`

A researcher believes due to Global Warming that the average temperature is increasing in Atlanta.

`\mu>90^(\circ)F`

Clearly by using definition ,

Null hypothesis :
`H_0: \mu=90^(\circ)F`
