Answer:
HDTV Converters
a. The probability that the driver will have enough working converters = 80% (100 - 20%).
b. The driver should load 10 boxes (or specifically 9.5 boxes) to ensure a 95% probability of having enough working converters.
Step-by-step explanation:
a) Data and Calculations:
Probability of HDTV converters known to not work property = 20%
This implies that 80% (100 - 20%) will work properly.
Number of converters to install today in an apartment building = 8
Number of converters placed in the truck = 10
b) The probability that the driver will have enough working converters = the probability of having properly working converters, which is 80%. To ensure a 95 percent probability of having enough working converters, out of 10 converters, the number of boxes to load on the truck is 9.5 (10 * 95%) boxes. Since there are no half boxes, it means that 10 boxes must be loaded, approximated to the nearest convenient number.
