iren [92.7K]

Answer:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

Step-by-step explanation:

Given that:

sample size n = 1600

sample mean \overline x = 20000

standard deviation = 5000

The objective is to choose from the given option about what most closely resembles the relevant box model.

The correct answer is:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000

Similarly, the standard error for the sample mean = \dfrac{s}{\sqrt{n}}

= \dfrac{5000}{\sqrt{1600}}

= \dfrac{5000}{40}}

the standard error for the sample mean = 125

15+0= 15
Ksju [112]

First of all, let's take a look on the question.

\large{15 + 0 = 15}

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.

So, the property is known as <u>Identi</u><u>ty</u> property because 0 is added to get the identity of the same number.

<u>The Correct Option:</u>

\large{ \boxed{ \red{ \bf{Option \: C}}}}

So, let's know more...

  • Commutative property ➝ a + b = b + a
  • Associative property ➝ a + (b + c) = (a + b) + c
  • Distributive property ➝ a(b + c) = ab + ac

So this is the general form of these properties which is general observed in the rational numbers.
