Answer:

6 13/14

Step-by-step explanation:

Add the whole numbers first.

6 + 2/7 + 9/14

Find the Least Common Denominator (LCD) of 2/7, 9/14. In other words, find the Least Common Multiple (LCM) of 7,14.

LCD: 14

Make the denominators the same as the LCD.

6 + 2 × 2/7 × 2 + 9/14

Simplify. Denominators are now the same.

6 + 4/14 + 9/14

Join the denominators.

6 + 4 + 9/14

Simplify

6 13/14

Answer:

6 13/14

Step-by-step explanation:

Convert 2/7 to 4/14 by multiplying both 2/7 by 2/2, to have a common denominator, then add your mixed numbers.

2/7 x 2/2 = 4/14

4/14 + 9/14 = 13/14

4 + 2 = 6

6 13/14

The calibration of a scale is to be checked by weighing a 13 kg test specimen 25 times. Suppose that the results of different we
Natali5045456 [20]

Solution :

a).

Given : Number of times, n = 25

            Sigma, σ = 0.200 kg

            Weight, μ = 13 kg

Therefore the hypothesis should be tested are :

$H_0 : \mu = 13 $

$H_a : \mu \neq 13$

b). When the value of $\overline x = 12.84$

 Test statics :

   $Z=\frac{(\overline x - \mu)}{\frac{\sigma}{\sqrt n}} $

  $Z=\frac{(14.82-13)}{\frac{0.2}{\sqrt {25}}} $

          $=\frac{1.82}{0.04}$

          = 45.5  

P-value = 2 x P(Z > 45.5)

            = 2 x 1 -P (Z < 45.5) = 0

Reject the null hypothesis if P value  < α = 0.01 level of significance.

So reject the null hypothesis.

Therefore, we conclude that the true mean measured weight differs from 13 kg.
