A researcher claims that the mean annual production of cotton is 3.5 million bales per country. A random sample of 44 countries has a mean annual production of 2.1 million bales. Assume the population's standard deviation is 4.5 million bales. At a significance level of \( \alpha = 0.05 \), can you reject the claim? (Answer the following four questions by choosing all of the answers that apply below) \[ [a] = \text{Claim} \] \[ [b] = H_0 \] \[ [c] = H_a \] \[ [d] = \text{Reject/Fail} \]
