6. yes there is because it shows there was a change
7. yes becuase itheres a possitive change
Result 1: Two sample T hypothesis test final lab [Info]
Two sample T hypothesis test:μ_{1} : Mean of AudBefore μ_{2} : Mean of AudAfter μ_{1}  μ_{2} : Difference between two means H_{0} : μ_{1}  μ_{2} = 0 H_{A} : μ_{1}  μ_{2} ≠ 0 (without pooled variances) Hypothesis test results:

Result 2: Two sample T hypothesis test final lab [Info]
Two sample T hypothesis test:μ_{1} : Mean of VisBefore μ_{2} : Mean of VisAfter μ_{1}  μ_{2} : Difference between two means H_{0} : μ_{1}  μ_{2} = 0 H_{A} : μ_{1}  μ_{2} ≠ 0 (without pooled variances) Hypothesis test results:

Result 3: Two sample variance hypothesis test final lab [Info]
Two sample variance hypothesis test:σ_{1}^{2} : Variance of AudBefore σ_{2}^{2} : Variance of AudAfter σ_{1}^{2}/σ_{2}^{2} : Ratio of two variances H_{0} : σ_{1}^{2}/σ_{2}^{2} = 1 H_{A} : σ_{1}^{2}/σ_{2}^{2} ≠ 1 Hypothesis test results:
