Res Exercise 10-24 Algo A sample of 39 paired observations generates the following data d 2.5 and useful to reference the appropriate table: z table or t table 50. Assume a normal distribution. (You may find it a. Construct the 90% confidence interval for the mean difference HD (Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.) Answer is complete but not entirely correct. 115 to 384 Confidence interval is 01 b. Using...
A sample of 21 paired observations generates the following data: d = 1.0 and 5 = 2.8. Assume a normal distribution. (You may find it useful to reference the appropriate table: z table or table) a.
