a) What is the lower endpoint of this confidence interval?b) What is the upper endpoint of this confidence interval?c) Based on the confidence interval, you would reject, at 5% level of significance, the hypothesis that the two samples are from populations with equal variance? We will now compute a 95% confidence interval for the ratio of. Here, we are no longer assuming equal variances, so o denotes the0}population variance of each X; and o denotes the population variance of each Y;.What is the lower endpoint of this confidence interval? Give answer to 3 decimal places.Answer: Suppose we observe two independent random samples X₁, ..., Xn, with each X¡Y₁ N(μ2, 0²). We will assume that μ₁, μ2 and ² are unknown.2We are given x = 10.1, y = 7.1, sWe would like to test the hypothesis Ho: M₁ = μ₂ versus H₁ μ₁ # M₂.N(μ₁,0²) and Y₁, ..., Yn with each=: 5.5 and s} = 6.4, with n₁ = 13 and n₂ = 19.

1. In a study of perception, 110 men are tested and 24 are found to have red/green color blindness (based on data from USA Today). Assume that this was done in a simple random manner. A 95% confidence interval estimate of the proportion of all men with red/green color blindness was found to be 0.14 to 0.30. If we learn that the actual population proportion of men with red/green colorblindness is equal to 0.12, then what can we conclude? A. The confidence interval was wrong. B. We would need to see the sample data to make any conclusions Pick either answer A or B as your answer and show your work to go with it
