ser-zykov [4K]

Answer:

Step-by-step explanation:

Let X represent for males and Y for females

Given that

Group   Group One     Group Two  

Mean 84.00          78.00

SD        4.00                    8.00

SEM 1.26             2.53

N            10              10  

SEM is calculated as \frac{s}{\sqrt{n} } for each group

H_0: \bar x = \bar y\\H_a: \bar x \neq \bar y

(Two tailed test at 5% significance level)

t = 2.1213\\  df = 18\\  standard error of difference = 2.828\\p=0.0480

Since p <0.05 we reject H0 and there is significant difference between the groups.

A.Exam scores were significantly higher in the male group, t(18) = 2.83, p < .05B

Answer:

The transformation

(x,y) \rightarrow (x-5,-y+1)

maps triangle XYZ onto triangle X”Y”Z”.

Step-by-step explanation:

Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.

Now Z = (-2, 2) and Z'' = (-7, -1).

The x-coordinate goes from -2 ⇒ -7.

The y-coordinate goes from 2 ⇒  -1.

The x-coordinate is just shifted by -5; thus, x \rightarrow x-5, and the y-coordinate first transforms as y \rightarrow -y, and is then shifted by 1; thus, it transforms as y \rightarrow -y+1.

So we have the full transformation

(x,y) \rightarrow (x-5,-y+1)
