Question 3 {1 point) v' Saved The confidence interval of a quantitative variable is centered on the mean and has a margin of error that is added and subtracted to determine the confidence limits for that mean. What is the margin of error for the variable OWL in vour data set? ?.3606 Question 4 {1 point) What is the test statistic you needed to use to calculate the previous value? 0 Cannot calculate because we dropped this variable or it was not in our data set. 0 a O 29/2 O tea/2111f Question 9 {1 point] x!\" Saved What is the value in the centre of the confidence interval for LOOK? (Whv would I ask this question if it is the same as all the others?] 0 Cannot be calculated Ops Os a 0? Question 10 (1 point} What values did vou calculate for the confidence limits for LOOK? [Show lower limit first and upper limit second.) :] :l Question 7 (1 point) Saved Can you calculate a confidence interval for "LOOK"? Yes O No Not enough information provided. Question 8 (1 point) Justify your last answer. If you did not understand how to answer the previous question you are likely not to get this one. This answer requires 2 simple calculations. Paragraph v BI UQuestion 5 (2 points) According to your calculations, what are the upper and lower confidence limits for the variable FOX in your data set? (Answer precision to 3 decimal places, even if those are Os.) Provide lower limit first, then upper limit. Put Lower Limit in the box below. Now put upper limit in the box below. Question 6 (4 points) Show your calculations for 1 ( and only 1) of the these two variables: SEAL or MAN. Include the number in the centre of the range, the values used to calculate the confidence interval and the final values.
