Answer:
The probability that the mean delivery time from the sample of 25 orders xˉ is farther than 2 minutes from the population mean cannot be calculated.
Step-by-step explanation:
As given in the question statement, the distribution of delivery times is strongly skewed to the right. The population distribution is skewed to right. Too much skewed distribution can cause the statistical model to work ineffectively and affects its performance. The probability can also not be calculated because the sample size is too small. Small sample size affects the results and makes them less reliable because it results in a higher variability and likelihood of skewing the results.

you have to use the quadratic equation to find the zeros
Step-by-step explanation:
Correct Answer:
Option B. It will have less variationThe standard deviation of distribution of sample means is given by:
Here,
s = Standard deviation of distribution of sample means
S = Population standard deviation
n = Sample Size
From equation we can see that Standard deviation of distribution of sample means is inversely proportional to the square root of sample size. This means if sample size is increased, the standard deviation of distribution of sample means will decrease. Hence a larger sample size will have less variation as compared to a small sample size.
Therefore, option B is the correct answer.
