A sample observation results in a point estimate of 0.53 for the mean value of paint thickness.
The mean value theorem states that there is one point on a curve where the tangent is parallel to the secant running through the two points.
A low-viscosity paint sample with the following thickness is provided to us.
0.810.870.901.051.111.141.301.301.481.481.591.601.661.691.781.84
a) Point estimate of the mean value of coating thickness.
To estimate the mean coating thickness, we use the mean value of the sample.
mean= sum of all observations/total number of observations
mean=8.16/16
mean=0.53
Construct a normal probability plot for the following sample of observations on coating thickness for low-viscosity paint. 0.810.870.901.051.111.141.301.30 1.481.481.591.601.661.691.781.84 Determine the z percentile associated with each sample observation. (Round your answers to two decimal places.)
