Pioneer company has given an aptitude test to 71 potential job applicants. The test score had an average of 81 and a standard de

Agata [3.3K]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

In point A:

$\to df = n - 1 = 71-1= 70$

In point B:

$\to t = \frac{(x -X)}{s} = \frac{(93-81)}{8} = \frac{12}{8}= 1.5$

In point C:

For df = 70, the top 5% critical t score

tcrit = 1.666914479

Thus,

$\to 1.666914479 = \frac{(x - 81)}{8}\\\\\to 1.666914479 \times 8 = (x - 81)\\\\\to 13.335315832 = (x - 81)\\\\\to 13.335315832 +81 =x \\\\\to x= 94.335315832$

In point D:

For df = 70, the top 5% critical t score

tcrit = -1.666914479

$\to -1.666914479 = \frac{(x - 81)}{8}\\\\\to -1.666914479 \times 8= (x - 81)\\\\\to -13.335315832= (x - 81)\\\\\to -13.335315832+81 = x \\\\\to x = 67.664684168\\\\$

In point E:

The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is

tcrit = -1.293762898

$\to -1.293762898 = \frac{(x-81)}{8}\\\\\to -1.293762898 \times 8= (x-81) \\\\\to -1.293762898 \times 8= (x-81) \\\\\to -10.350103184=x-81\\\\\to -10.350103184+81=x\\\\\to x=70.649896816$

In point F:

The lower cutoff is 0.90 in the center, which would be around 80 %. The critical point therefore is

tcrit = 1.293762898

$\to 1.293762898 = \frac{(x-81)}{8}\\\\\to 1.293762898 \times 8= x-81\\\\\to 10.350103184 =x-81\\\\\to 10.350103184 +81=x\\\\\to x = 91.350103184\\$

!!!HELP AS SOON AS POSSIBLE!!!<br><br> Simplify: -2/9 divided by 3 1/4

ohaa [14]

<h3>Answer: the fraction -8/117</h3>

----------------

First, convert to an improper fraction

3 & 1/4 = 3 + (1/4)

3 & 1/4 = (12/4) + (1/4)

3 & 1/4 = 13/4

The mixed number 3&1/4 turns into the improper fraction 13/4

---------------

-2/9 divided by (3&1/4) = -2/9 divided by 13/4

To divide two fractions, you flip the second one and then you multiply

"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens

Then you multiply straight across. The numerators stick together. The denominators stick together.

numerators: -2*4 = -8

denominators: 9*13 = 117

We end up with the fraction -8/117

This cannot be reduced as there are no common factors (other than 1) between 8 and 117.
