Population parameters are difficult to calculate due to A. cost prohibitions on data collection. B. the infeasibility of collecting data on the entire population. C. the fact that samples are difficult to draw due to the nature of the data. D. both cost prohibitions on data collection and the infeasibility of collecting data on the entire population

D. both cost prohibitions on data collection and the infeasibility of collecting data on the entire population

Step-by-step explanation:

When stablishing population parameters, one of the main obstacles is the difficulty of gathering data on every single subject within the population, which is often infeasible. On most cases, even if it were feasible to collect data on the whole population, it would be a highly costly procedure making it extremely unlikely to get funded.

Therefore, the answer is D. both cost prohibitions on data collection and the infeasibility of collecting data on the entire population.

step-by-step explanation:

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
