Good day! I just want to ask help as I'm a bit confused in differentiatng null and alternative hypothesis.
1. According to a university study, the mean charitable contribution per family among families with income of ₱50 000 or more in the Philippines in 2008 was ₱1 500. A researcher believes that the level of giving has changed since then. Determine the null and alternative hypotheses.
2. The Food and Drug Administration requires that a jar of peanut butter labeled as containing 25 ounces must contain at least 25 ounces. A concerned citizen feels that a peanut butter manufacturer is cheating by underfilling the jars. Determine the null and alternative hypotheses.
My answer here is
Null: miu greater than or equal to 25 ounces
Alternative: miu less than 25 ounces.
But i am not sure of it and also can't understand no. 1 pls.
