The value of test statistic is 5.45

Data;

n1 = 25
n2 = 30
x1 = 6.2
x2 = 3.8
s1 = 2
s2 = 1

<h3>Test Statistic</h3>

The formula to calculate the test statistic is given as

$t = \frac{x_1 - x_2}{\sqrt{\frac{s_1^2}{n_1}+ \frac{s_2^2}{n_2} } } \\$

Let's substitute the values and solve for t

$t = \frac{x_1 - x_2}{\sqrt{\frac{s_1^2}{n_1}+ \frac{s_2^2}{n_2} } } \\t = \frac{6.2 - 3.8}{\sqrt{\frac{2^2}{25} + \frac{1^2}{30} } } \\t = \frac{2.4}{0.44} = 5.45$

The value of test statistic is 5.45

The sides of a triangle are in the ratio 3:4:5. What is the length of each side if the perimeter of the triangle is 30 cm

horsena [70]

One way:

3x + 4x + 5 x = 30
12 x = 30
Divide by 12
x = 2.5

3x = 7.5 (2.5x3)
4x = 10 (2.5x4)
5x = 12.5 (2.5x5)

7.5cm + 10cm +12.5cm = 30cm There are your three sides.
