dont just calculate , please show step by step
Suppose, random variable X denotes coating thickness for low-viscosity paint.
From sample data, we obtain mean and standard deviations as follows.
Sample size
Sample mean is given by
Sample standard deviation is given by
Corresponding to each sample value, we calculate
We now calculate z-score and z-percentile for each sample value as follows.
