(81m^6)^1/2 = (3^4*1/2) (m^6*1/2) = 3²m³
Answer:
The 95% confidence interval obtained with a sample size of 64 will give greater precision.
Step-by-step explanation:
We are given the following in the question:
A 95% confidence interval is calculated with the following sample sizes

The population mean and standard deviation are unknown.
Effect of sample size on confidence interval:
- As the sample size increases the margin of error decreases.
- As the margin of error decreases the width of the confidence level decreases.
- Thus, with increased sample size the width of confidence level decreases.
If we want a confidence interval with greater precision that is smaller width, we have to choose the higher sample size.
Thus, the 95% confidence interval obtained with a sample size of 64 will give greater precision.
Answer:
Each friend got 6 cars each
Step-by-step explanation:
17-5= 12 cars
He gave 12 cars away.
Since there are 2 friends, you divide the cars given away by 2, hence
12/2= 6
