A box of tickets has an average of 420; the SD is 84. If we draw at random (with replacement) 50 times and compute the average o

disa [49]

Answer:

Average of the draws equals 420

Standard Error = 11.88

Step-by-step explanation:

Given

$\mu = 420$

$\sigma = 84$

$n =50$

Solving (a): The average of the draws

This implies that we calculate the sample mean

This is calculated as:

$\bar x = \mu$ --- Sample Mean = Population Mean

So, we have:

$\bar x = 420$

Solving (b): The standard error

This is calculated as:

$SE=\frac{\sigma}{\sqrt n}$

So, we have:

$SE=\frac{84}{\sqrt {50}}$

Using the calculator, we have:

$SE=11.88$
