You need to make a decision based on published access times for both services at different times and for varying file sizes.To make your decision, you purchase a statistical study, which indicates that average download time for Pie in the Sky is 0.77 sec.per MB and for Cloudy but Steady Skies is 0.84.Assume that n₁ = n₂ = 50, $\sigma$ ₁ = 0.2 and $\sigma$ ₂ = 0.3.With $\alpha$ = .05, the appropriate decision is ______.

• A)reject the null hypothesis \(\sigma\)₁² < \(\sigma\)₂²
• B)accept the alternate hypothesis \(\mu\)₁ − \(\mu\)₂ \(\gt\)0
• C)reject the alternate hypothesis n₁ = n₂ = 50
• D)fail to reject the null hypothesis \(\mu\)₁ − \(\mu\)₂ ≤ 0
• E)do nothing
