SOLVE STEP BY STEP IN DIGITAL FORMAT 10. The semarnat has set the average number of bacteria per cm3 of water at 70, as a limit. An average value greater than 70 can cause hepatitis in people who eat clams. It has been shown that the probability distribution of the number of bacteria can be modeled as a normal one. In order to decide if certain waters meet the standard, nine water samples were taken, and the following bacteria counts were obtained: 69,74,75,70,72,73,71,73,68. Do the data show that the waters are safe for fishing, at the 5% level of significance?
