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.
Answer: your wuestion isn’t specific enough.
Step-by-step explanation:
Answer:
110kg
Step-by-step explanation:
You multiply 100 by 0.1 (because this is 10% as a decimal number) and you get 10. Add 10 to 100
Volume of tractor = length x width x height = 301.5 x 96.99 x 105.04 = 3,071,630.624
For baseballs of 9 inches:

Volume =

Number of 9 inches baseballs =

For baseballs of 9.25 inches:

Volume =

Number of 9.25 inches baseballs =

Therefore, the tractor can contain between 229,824 and 249,513 baseballs.
To convert fractions into decimals simply divide the numerator (5) by the denominator (8). If you type in "5/8" into a calculator you will receive a compute of 0.625 which you can round to .6
