The degrees of freedom can be used to test a hypothesis about the mean.

<h3>What is degrees of freedom?</h3>

Degrees of freedom refers to the maximum number of logically independent values that have the freedom to vary, in the data sample.

Given, the sample size is 20, then degree of freedom will be

The degrees of freedom represented as

dof = n – 1

dof = 20 – 1

dof = 19

Thus, the degrees of freedom can be used to test a hypothesis about the mean.

Answer:

What is the degrees of freedom when the sample size is 20?

19

For example, if we have a sample of size n = 20 items, then we calculate the degrees of freedom as df = n – 1 = 20 – 1 = 19 and we write the distribution as T ~ t19.

Find the 45th percentile of the data set. Give your answer to three decimal places.
Schach [20]

The 45th percentile of the data given above (P₄₅) is 16.225.

<h3>What is percentile in statistics?</h3>

Percentile refers to the mathematical or statistical term that is used to indicate the position of a data in relation to others from the sample given.

<h3>How did we arrive at the above figure?</h3>

Step 1 - First all data must be arranged in ascending order:

See the attached table for this.

Step 2 - We compute the position or rank of the 45th percentile.

The formula for percentile position is given as:

((n +1 ) *P)/100

= ((25+1) * 45)/100

= 11.70

Step 3 - Deploy the interpolation method because the position above is not an integer.

The numbers in positions 11 and 12 are where you'll find the 45 percent percentile. Based on the data arranged in ascending order, the values are 15 and 16.75.

The percentile we're seeking for is situated at the value of 11.7 - 11 = 0.7, which is the percentage of the space between 15 and 16.75.

Therefore,

(P₄₅) = 15 + 0.7 x (16.75 - 15)

(P₄₅) =16.225.

During the age of exploration, both the spanish and the french allowed religious tolerance in their colonies. enslaved indigenou
Law Incorporation [45]

Both the Spanish and the French attempted to spread religion throughout the Americas throughout the age of exploration.

From roughly the 15th century to the 17th century in European history, the Age of Discovery (or the age of exploration), sometimes known as the early modern period and mostly coinciding with the Age of Sail, was a time when sailor-loving Europeans traveled the world in search of new lands to discover.

The massive foreign expedition during age of exploration, led by the Portuguese and the Spanish and subsequently joined by the Dutch, the English, and the French, came to be seen as a significant influence on European civilization, most notably the encounter and colonization of the Americas. It also heralds a rise in the use of colonialism as an official government policy in various European nations. It is sometimes equated with the initial wave of European colonialism as a result.
