Problem 7.4

A CI is desired for the true average stray-load loss (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. Assume that strayload loss is normally distributed with 3.0. a. Compute a 95% CI for when n 25 and x 58.3. b. Compute a 95% CI for when n 100 and x 58.3. c. Compute a 99% CI for when n 100 and x 58.3. d. Compute an 82% CI for when n 100 and x 58.3. e. How large must n be if the width of the 99% interval for is to be 1.0? 5. Assume

Step-by-Step Solution:
Step 1 of 3

Groups Randomize control group Split individuals into two groups separately Control vs. treatment Compare the two averages correlation between the groups (Measure the strength before and after to get the experiment) Matching Observed and match into pairs with two treatments (Longitudinal and measures) Each group has their own control group within Find the change between the strength and average added between both old and new Compute: d= x1­x2 X1= response from one event X2= response from another event Analyzing D is what the gain and strength is Next: one variable to look over Find dbar and Sd After: use dbar and Sd to inference about Mud (Standard deviation of differences) To what value should we compare dbar Ho: Mud= 0 does
