For each test, sketch the Normal curve for the sampling distribution of x when H0 is true. This curve has mean 5.0 and standard deviation 0.6/ n . Mark the observed x = 4.8 on each curve. What happens to the significance of the result x = 4.8 as the sample size increases?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
