Answer:
1/2m+100
Step-by-step explanation:
Answer:
Mean 105
Standard deviation 1.89
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation
In this problem, we have that:
If the sample size is n 81, find the mean and standard deviation of the distribution of sample means.
By the Central limit theorem
mean 105
Standard deviation
Answer:
(a) (b)
Step-by-step explanation:
GIVEN: Suppose that two cards are randomly selected from a standard card deck.
TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.
SOLUTION:
(a)
Probability that first card is club
As sampling is done without replacement.
probability that second card is club
Probability that first card is club and second card is club
(b)
Probability that first card is club
As sampling is done with replacement.
probability that second card is club
Probability that first card is club and second card is club
