Why is the value considered for Critical value, or Z* is positive 1.96? Why not negative 1.96? Calculating the Margin of Errormargin of error = (critical value)(standard error of statistic)In the verifying signatures example,we are asked to construct a 95%confidence interval. To find thecritical value z* for a 95%confidence interval, find theboundaries encompassing themiddle 95% of the standard normaldistribution.-z* = -1.96area = 0.95z* = 1.96The critical value is z* = 1.96.

We have given, z = 1.96 or -1.96. And we have to find the value considered for Critical value, or…

The average time to handle a call in a call center has a specification of 6 ± 1.25 minutes. The loss resulting from a mishandled call is $10. Five consecutive calls were drawn from the process and the results, in minutes, are as follows: 7.3 6.6 6.2 4.3 6.7 1. According to the conventional perspective, the quality loss per call = 2. The value of k in the Taguchi loss function = 3. The Quality loss per call according to the Taguchi perspective =
