Based on the sample mean, the manager suspects that the call center is operating at a lower Conversion Rate than the target of 30%. In order to test this, she should set up the following hypotheses:

H₀: µ < 30

H_A: µ 30

H₀: x 30

H_A: x < 30

H₀: µ 30

H_A: µ < 30

H₀: µ = 30

H_A: µ 30

H₀: µ > 30

H_A: µ < 30

Solution

H0: µ 30

HA: µ < 30
