Question

It has been said in Seattle, Washington that at least 50% of the days are rainy.  A researcher wanted to prove this statement.

Alternate Hypothosis:?

The image presents hypotheses for a statistical test regarding rainfall. 

1. Null Hypothesis (H₀): 
   - \( M_{\text{rain}} \geq 50\% \)

2. Null Hypothesis (H₀): 
   - \( M_{\text{rain}} < 50\% \)

3. Alternative Hypothesis (Hₐ): 
   - \( M_{\text{rain}} \geq 50\% \)

4. Alternative Hypothesis (Hₐ): 
   - \( M_{\text{rain}} < 50\% \)

These statements are used to test whether the mean or median rainfall (\( M_{\text{rain}} \)) meets certain percentage criteria, either greater than or equal to 50% or less than 50%.
