If the sampled population has a mean of 48 and standard deviation of 16, then the mean and the standard deviation for the sampli
Step2247 [10]

Answer:

48 and 4

Step-by-step explanation:

If we assume that \bar X to be the random variable that proceed the normal distribution with mean \mu and  a standard deviation \dfrac{\sigma }{\sqrt{n}}

Given that:

mean =48

standard deviation = 16

sample size = 16

The population mean is same as the population mean in sampling distribution that is 48.

The standard deviation of the sampling distribution is therefore calculated as:

standard deviation = \dfrac{\sigma }{\sqrt{n}}

standard deviation = \dfrac{16 }{\sqrt{16}}

standard deviation = \frac{16}{4}

standard deviation = 4

Thus; the mean and the standard deviation of the sampling distribution is 48 and 4

Answer:


Step-by-step explanation:

Given that a box has cards numbered 1 ,2,3

Also a bag has three balls labelled A, B and C

Sample space = {(1,A)(1,B)(1,C) (2,A)(2,B)(2,C)}  n(S) = 9

Mary will randomly pick up a card from the 3 cards and also pick up a ball from the bag of 3 balls.

The sample space contains the combination of letter on the card and number on the ball.

Event that the number chosen is 1 is

{(1,A)(1,B)(1,C)}:  n(event of choosing 1)=3
