Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of t

Zolol [24]

Answer:

The value is $E =19.6$

Step-by-step explanation:

From the question we are told that

The mean of Jo cows is $\= x_1 = 1350$

The standard deviation of Jo cow is $s_1 = 50$

The mean of Val cows is $\= x_2 = 1420$

The standard deviation of Val cows is $s_2 = 50$

The sample size for both Val and Jo is n = 25

Let assume that the level of significance is $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

Hence margin of error for Jo is

=> $E = 1.96 * \frac{50}{\sqrt{25} }$

=> $E =19.6$
