A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are

in control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results: Machine Measurements #1 17 15 15 17 #2 16 25 18 25 #3 23 24 23 22 What is the sample mean for machine #1?

Answer:

16

Step-by-step explanation:

The sample mean for machine #1 is obtained by simply adding up the four sampled units of output for the machine (17, 15, 15, 17) and then dividing the result by four:

m=\frac{17+15+15+17}{4}\\ m=16

Therefore, the sample mean for machine #1 is 16.

Which correlation coefficient represents a moderate negative correlation? r = –0.04 r = –0.24 r = –0.64 r = –0.94
fomenos

The correlation coefficient is a number that indicates the direction

and closeness of points of a line of best of fit.

So it tells us two things.

It tells us the direction of the line of best fit

and it tells us the closeness of the points.

Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.

It will be a negative correlation because the slope is negative.

Answer:

\=x=82

Step-by-step explanation:

From the question we are told that:

Data

\begin{center}\begin{tabular}{ |c|c|c|c|c|c| }  87& 91& 86& 82& 72&91 \\ 60& 77& 80& 79& 83&96 \end{tabular}\end{center}

Generally the equation for Point estimate \=x is mathematically given by

\=x=\frac{\sum_x}{n}

\=x=\frac{87 +91+ 86+ 82 +72 +91+ 60+ 77 +80+ 79+ 83 +96}{12}

\=x=\frac{984}{12}

\=x=82
