A random sample of 41 glass sheets is obtained, and their thicknesses are measured. The sample mean is $ \bar{x} = 3.04 $ mm and the sample standard deviation is $ s = 0.124 $ mm. Construct a 99% two-sided t-interval for the mean glass thickness. Do you think it is plausible that the mean glass thickness is 2.90 mm?

Given information Sample size (n) = 41 Mean x̅ = 3.04 mm Standard deviation (s) = 0.124 mm…

Answered: A random sample of 41 glass sheets is…

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability.
