A craft store sells clay in spheres with radius. A sculptor uses these spheres of clay to create composite figures
Three composite figures that the sculptor makes are
shown in the diagrams
1. How many spheres of clay does
the sculptou need to make two
copies of Figure A? Explain
Figures
Figure A
20
2. How many spheres of clay does the sculptor need to make two
copies of Figure B? Explain.
3. How many copies of Figure C can the sculptor make from
15 spheres of clay? Explain.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
