deter- minations of BOD,

 

8.56       Refer to Exercise 8.55. Along with the deter- minations of BOD, the discharge of suspended solids ( SS) was also monitored at the same site. The mean and standard deviation of the

43 determinations of SS were found to be 5710 and 1720 pounds per day, respectively. Do these results strongly support the com- pany’s claim that the true mean SS is lower than 6000 pounds per day? (Answer by calcu- lating and interpreting the P – value.)

 

 

 

8.57       Suppose that n units are randomly sampled and x number of the sampled units are found to have the characteristic of interest. In each case, (i) define p in the context of the problem,

(ii) provide a point estimate of p and (iii) de- termine the 95% error margin.1

(a)    A survey is conducted of n = 986 adults and x = 295 reported that reading is a favorite leisure time activity.

(b)    A survey of n = 440 pet owners revealed that x = 293 buy their pets holiday pre- sents.
