This is the data that was provided, please copy and paste this data on Minitab then choose stat, basic statistics, graphical summary I repeat choose stat, basic statistics, graphical summary in variables enter output voltage click OK. Here you go. This is the graphical summary of output voltage of the power supply. The mean output voltage is 10.259 95% confidence intervals of 9.727 and 10.79 to the standard deviation is 0.999 95% Confidence intervals of 0.738 and 1.546. Using the significance level of 0.05.
The Anderson darling normality test with a p value of 0.767 indicates that the output voltage data follows a normal distribution. That brings us to the end of this section. Thank you for attending. See you in the next one.
