\fQuestion 4 N(u,) indicates a normal distribution with a mean, u and standard deviation, o. We can calculate areas in the tails of any Not yet normal distribution using StatKey. Open StatKey, go to 'Theoretical Distributions' and choose 'Normal'. You can then use the answered 'Edit Parameters' button to change the mean and standard deviation as necessary. Marked out of 2.00 Remove flag For the following normal distributions find the probabilities (areas) to the left of 90. N(100,1) Choose... N(100,15) Choose... N(100,5) Choose... + N(100,25) Choose... 4Question 6 Not yet answered Marked out of 3.00 Y Remove flag The general form for a confidence interval is: Sample Statistic 1 z" . SE Calculate the lower and upper limits of a 95% confidence interval for a population proportion given: 17': 0.53 SE = 0.05 Round your answer to 3 decimal place. 95% Confidence interval = ( For an example of how to do a calculation like this see this demo in Excel. What inference can we make about a 95% confidence interval in general? 0 \\/ There is a 0.95 probability the true population parameter is somewhere between the lower and We can be 95% confident the sample statistic is somewhere between the lower and upper limits. We can be 95% confident the true population parameter is exactly between the lower and upper We can be 95% confident the true population parameter is somewhere between the lower and
