Which of these is equivalent to 3^2 ? Select all that apply

san4es73 [151]

Answer:

D, E &F

Step-by-step explanation:

Lets's go down the list and evaluate each choice

A. (3^8) / (3^4) = 3^ (8-4) = 3^4 (≠ 3^2)

B. 6²/2 = (2 x 3)²/2 = (2²·3²)/2 = 4·3²/2 = 2.3² (≠ 3^2)

C. (3^5) ·(3^3) = 3^ (5+3) = 3^8 (≠ 3^2)

D 3·3 = 3^2 (Answer)

E. (3^12) / (3^10) = 3^ (12 -10) = 3^2 (Answer)

F. (3^-3) / (3^-5) = 3^ [ -3 -(-5) ] = 3^ (-3 + 5) = 3^2 (Answer)

What is an important difference between statistics andâ parameters?

Ilia_Sergeevich [38]

Answer:

A characteristic , usually unknown of the population.

Characteristic of the population , such as its mean ,variance and standard deviations are population Parameters .

An observed characteristic of a sample are known as statistics

Estimate the use of a sample characteristic (statistic) to guess or approximate a population characteristic (parameter)

Step-by-step explanation:

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-1

When a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

Example :-2

If the students of a certain school are given blood tests and the type of blood is of interest, then a descriptive representation.

Population:-

Population is consists of the total observation's with which we are concerned

The number of observations in the population is defined to be the size of the population

Sample:- A sample is a subset of population.

Samples are classified in two ways

Large sample : if the size of the sample n≥ 30 is called the large sample.

small sample: if the size of the sample n<30 is called the small sample.

Statistics uses different names and symbols to distinguish characteristics

of the population from those of a sample.

Parameters :-

A characteristic , usually unknown of the population.

Characteristic of the population , such as its mean ,variance and standard deviations are population Parameters .

In symbolically mean of the population parameter is denoted by μ

In symbolically variance of the population parameter is denoted by σ²

In symbolically standard deviation of the population parameter is denoted by σ

Statistic :-

An observed characteristic of a sample are known as statistics

Estimate the use of a sample characteristic (statistic) to guess or approximate a population characteristic (parameter)

In symbolically mean of the sample statistic is denoted by x⁻

In symbolically variance of the sample statistic is denoted by S²

In symbolically standard deviation of the statistic is denoted by S
