For conducting a​ two-tailed hypothesis test with a certain data​ set, using the smaller of n1minus1 and n2minus1 for the degree

s of freedom results in dfequals​11, and the corresponding critical values are tequalsplus or minus2.201. Using the formula for the exact degrees of freedom results in dfequals​19.063, and the corresponding critical values are tequalsplus or minus2.093. How is using the critical values of tequalsplus or minus2.201 more​ "conservative" than using the critical values of plus or minus​2.093?

Answer:

Step-by-step explanation:

Using the critical values of t=±2.201 is more "conservative" than using the critical value of ±2.093 because it is more likely to reject the null hypothesis using the greater value i-e t=±2.201

What are natural numbers in a set less than 3
sergeinik [125]
Natural number are basically " counting numbers ". They have no decimals, no fractions, and no negative numbers. It is debated whether 0 is included.

so ur natural numbers less then 3 are {1,2 }...not 100% sure if u include 0. I do not think u do.

Answer:

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Step-by-step explanation:

Let us take the point of projection of the ball as origin of the coordinate system, the upward direction as positive and down direction as negative.

Initial velocity u with which the ball is projected upwards = + 120 ft/s

Uniform acceleration a acting on the ball is to acceleration due to gravity = - 32 ft/s²

The ball shall keep rising tills its velocity becomes zero. Let it rise to a height h feet from point of projection.

Using the formula:

v² - u² = 2 a h,

where

u = initial velocity of the ball = +120 ft/s

v = final velocity of the ball at the highest point = 0 ft/s

a = uniform acceleration acting on the ball = -32 ft/s²

h = height attained

Substituting the values we get;

0² - 120² = 2 × (- 32) h

=> h = 120²/2 × 32 = 225 feet

The height of the ball from the ground at its highest point = 225 feet + 12 feet = 237 feet.

Let the sample be 11, 3, 4, 3, 5, 7, 8, 12. What is the range of the sample?
grin007 [14]

Solution

- The Range of a dataset is simply the difference between the largest number and the smallest number in the dataset.

- In the dataset given, the largest number is 12 while the smallest number is 3.

- Thus, the Range of the dataset is

12-3=9

Range = 9
