Answer:
The standard error of the sampling distribution of sample mean is: 6.5
Step-by-step explanation:
We use the Central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation, which is also called standard error of the sampling distribution of sample mean is
In this problem, we have that:
The standard error of the sampling distribution of sample mean is: 6.5
Answer:
The missing side is 7
Step-by-step explanation:
The smaller triangle has the same exact angles and the bigger one. If you notice each side with a value is three times the smaller one. 8m times three equals 24m. So if we divide 21 by 3 we get 7
Answer:
44.3%
Step-by-step explanation:
For a single selected traveler the change of him being high volume is 0.85, for 5 is the product of each individual probability.
P=(0.85)^5=0.443 → 44.3%
