Answer:
The correct option is C) large sample size (n) with small variance.
Step-by-step explanation:
Consider the provided information.
It is given that the other factors are held constant, and we want the narrowest confidence interval for a population mean.
Confidence interval for a population mean is directly proportional to variance and inversely proportional to the sample size.
If we increase the variance, CI will increase. But we want the narrowest CI, so variance should be small.
As CI is inversely proportional to sample size, therefore if we increase the sample size CI will decrease.
Hence, the correct option is C) large sample size (n) with small variance.
Answer:
Yes
Step-by-step explanation:
If no number was chosen by more than 3 people and more people chose the number 5 than the number 4, then in the worst scenario (least amount of people chose the number 1) the number 4 was chosen 2 times and the number 2, 3 and 5 were chosen 3 times. That makes a total of 3*3+2 = 11, so 1 person choose the number 1. This was the worst scenario, that guarantees that at least 1 person choose the number 1.
