The sample size is too small and will show a large variation.
The sample size is too small and can lead to false inferences.
A larger sample will give more reliable information.
Step-by-step explanation:
-In statistical sampling, sample size is of critical importance.
-A large sample size increases the accuracy of mean values as it eliminates or flattens out outliers.

Answer:
8x+15=7 8x=-8 x =-1
Step-by-step explanation:
Answer: It will take 10 minutes.
Explanation:
Cone A: 2.5mL x 10 minutes = 25 mL of ice cream falls in 10 minutes. 30mL-25mL=5mL
Cone B: 1.5mL x 10 minutes = 15 mL of ice cream falls in 10 minutes. 20mL-15mL=5mL
in 10 minutes, they’ll both be at 5mL
The answer is b, because division checks multiplication.
