Create the smallest pyramid possible with the tool, and record the values of the base length, base width, height, and volume (in terms of π). Then scale the original pyramid by the given scale factors, and record the resulting volumes (in terms of π), to verify that the formula V' = V × k3 holds true for a pyramid.

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
