Twenty-five samples, each of size 5, were selected from a process that was in control. The sum of all of the data collected was 750 Ibs. a. What is an estimate of the process mean (in terms of pounds per unit) when the process is in control? b. Develop rhe š control chart parameters (x , UCL, and LCL) when the process is in control. Assume that the process standard deviation is 0.6 when the process is in control, and that the mena of the process is the estimate developed in part (a) ? c. A sample of 5 units was taken from the process with the following results: 30.10 30.05 30.09 30.15 30.13 Based on this sample is this process "in control" or does it need to be adjusted?

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
