A hypothesis test is to be performed. Determine the null and alternative hypotheses. A health insurer has determined that the "reasonable and customary" fee for a certain medical procedure is $1200. They suspect that the average fee charged by one particular clinic for this procedure is higher than $1200. The insurer wants to perform a hypothesis test to determine whether their suspicion is correct.

H0: μ > $1200
Ha: μ = $1200

H0: μ = $1200
Ha: μ ≥ $1200

H0: μ ≤ $1200
Ha: μ > $1200

H0: μ = $1200
Ha: μ < $1200
