3 1/4 ounces = 3.25 Ounces.
3.25 x 5 = 16.25 ounces (16 1/4 ounces)
Answer: 500
Step-by-step explanation:
it is closest and is under 550. if it were 551 through 599 it would be 600
Solution :
a).
Given : Number of times, n = 25
Sigma, σ = 0.200 kg
Weight, μ = 13 kg
Therefore the hypothesis should be tested are :


b). When the value of 
Test statics :



= 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.
Here is your answer:
In order to find your answer we will have to solve each option separately to see which one equals 6 × 5.
<---- Not the answer
<----- Not the answer
<---- Your answer
Therefore your answer is option C "6 + 6 + 6 + 6 + 6 ."
Hope this helps!
