If a sample has 25 observations and a 99% confidence estimate for μ is needed, the appropriate value of the t-multiple required is . place your answer, rounded to 3 decimal places, in the blank. for example, 3.456 would be an appropriate entry.

Two tailed t = 2.797

One tailed t = 2.492

Step-by-step explanation:

The t-value can be defined as the ratio of the difference between the mean of the two sample sets and the difference that exists within the sample sets.

t at 99% confidence interval. For;

degree of freedom df = 25-1 = 24

Two sided test

t ( 99% +1/2% = 99.5)

Check t at 0.995 df = 24

t = 2.797

One tail test

t ( at 0.990) df = 24

t = 2.492

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
