Answer:
b. Invalid, because the sample may not be representative of the population.
Step-by-step explanation:
A sample of around 10% of the population is needed to be representative.
In this question:
We have a population of 500,000, and a sample of 10,000.
10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.
25 sales. you start with 50 and get $2 per sale in that week. if you make 25 sales, 25*2= 50. then do 50+50=$100
The answer to your problem will be negative slope you’ll thank me later
+ 215 = 218
