IQ scores are normally distributed with a mean of 105 and a standard deviation of 17. Assume that many samples of size n are taken from a large population of people and the mean IQ score is computed for each sample. If the sample size is n 81, find the mean and standard deviation of the distribution of sample means.

Answers

Answer:

Mean 105

Standard deviation 1.89

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = (\sigma)/(√(n))$

In this problem, we have that:

$\mu = 105, \sigma = 17$

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

$s = (17)/(√(81)) = 1.89$

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done without replacement? (b) What is the probability that the first card is a clubclub and the second card is a clubclub if the sampling is done with replacement?

Answers

Answer:

(a) $(1)/(17)$ (b) $(1)/(16)$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ 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 $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=(13)/(52)$

$=(1)/(4)$

As sampling is done without replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=(12)/(51)$

$=(4)/(17)$

Probability that first card is club and second card is club $=P(A)* P(B)$

$=(1)/(4)*(4)/(17)=(1)/(17)$

(b)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=(13)/(52)$

$=(1)/(4)$

As sampling is done with replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=(13)/(52)$

$=(1)/(4)$

Probability that first card is club and second card is club $=P(A)* P(B)$

$=(1)/(4)*(1)/(4)=(1)/(16)$
