Provided below are summary statistics for independent simple random samples from two populations. Use the pooled t-test and the pooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. x₁ =20,s₁ = 5, n₁ = 20, x₂ = 24, s₂ = 6, n₂ = 14 a. Left-tailed test, α = 0.05 b. 90% confidence interval a. What are the correct hypotheses for a left-tailed test? OA. Ho: H₁
