Answer #1

Q.2) A 95% confidence interval for μ1 - μ2 is given by (-2.3, 4.5).

Since, zero is lies in above interval, we can conclude that, there is no significant differences between two population means. That is, μ1 = μ2.

Therefore, this confidence interval implies that there is not a significant difference between the mean for population 1 and the mean for population 2.

    I need the completed and correct answer asap. thank you A 95% confidence interval for a population mean is from 101 to 104. What can we conclude from this? For 95% of all possible samples from this population, the confidence interval calculation will produce an interval contaming the population mean, so, based on this sample, we believe the population mean is between 101 and 104 The population mean is between 101 and 104 95% of all possible samples from this...
