SCCC 312A Homework 5:

** JK stands for the Johnson and Kuby textbook **

This assignment contains a lot of problems that seem like busywork.  But the goal 
is to practice again and again finding these probabilities so that it becomes 
second nature.

JK exercises:

5.60, 5.63, 5.67, 5.68, 5.70(b,c,d)[use p=0.20], 6.3, 6.5, 6.15, 6.20, 6.26, 
6.46 [use mu=400],6.50, 6.54, 6.80, 6.106(b), 6.110(c) [use the normal approximation], 
7.22, 7.30, 7.32, 7.36(a,b)


NOTE: For the chapter 5 problems, you should use Table 2 in Appendix B 
to determine the binomial probabilities.

NOTE:  For the normal probability problems, I want to see your pictures with 
shaded areas!!

NOTE: Hint for 6.54:  Here, mu=16.0.  Find the z-value with area .05 to the left; 
this z-value corresponds to the given x value of 15.8.  Now use the 
standardization formula to solve for sigma.
