Answer:
Therefore we fail to reject the Null hypothesis
Because the is no sufficient evidence to support the claim of the alternative hypothesis
Step-by-step explanation:
From the question we are told that
Sample size
Mean time 1
Mean time 2
Standard deviation
Standard deviation
Level of significance 0.05
The null hypothesis is
Alternative hypothesis
Generally the test statistics is mathematically represented as
From Table the Z-critical value at
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis at
Therefore we fail to reject the
Because the is no sufficient evidence to support the claim of
Answer:
Step-by-step explanation:
Find attached:
For algebraic division use KCF method.
K - Keep the first fraction
C- Change division to multiplicatin
F -Flip the second fraction.
3) Indenty used: (a -b)² =a² -2ab + b²
Where a = m and b =2
4) Identity used: (a +b)² = a² + 2ab +b²
Where a = w and b = 1
5) Identity used: a² - b² = (a +b)*(a -b)
Where a = z and b = 2
