guajiro [1.7K]

Answer:

The value of the test statistic is <em>z</em> = 3.34.

Step-by-step explanation:

The information provided is:

$\bar x=13.4\\\sigma = 4.47\\n=46$

The test statistic is:

$Z=\frac{\mu-\bar x}{\sigma/\sqrt{n}}$

$=\frac{15.6-13.4}{4.47/\sqrt{46}}\\\\=3.33806\\\\\approx 3.34$

Thus, the value of the test statistic is <em>z</em> = 3.34.

Five times the larger number is 11 more than three time the smaller number. Also three times the smaller is 16 less four times t

alisha [4.7K]

Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
