Answer:

3) 124

Step-by-step explanation:

a1 = 10

a2 = a1+6 = 10+6 = 16

a3 = a2+6 = a1+6+6 = a1 + 2×6 = 22

a4 = a3+6 = a2+6+6 = a1+6+6+6 = a1 + 3×6 = 28

...

=>

an = an-1 + 6 = a1 + 6(n-1)

=>

a20 = a1 + 6(20-1) = 10 + 6×19 = 10+114 = 124

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.
