AEqual to 275 exactly
BNot measurable
CGreater than 275 lb
DLess than 275 lb
Answer & Solution
Correct answer: C. Greater than 275 lb
1. The alternative states the effect the researcher is looking for.
2. The question asked is whether the bench press mean is more than 275 pounds.
3. So the alternative hypothesis is that the mean is greater than 275.
4. The null takes the opposite, no-effect position at or below that value.
