Answer: nonresponse bias

Step-by-step explanation:

According to the information obtained, we can say that it is a non-response bias, since the sample obtained to extrapolate the result was not homogeneous, so these biases arise when the type of response to the non-response is affected in a social experiment. meet a standard among the population muesta¡ra.

Cognitive biases are found in ideas that make us partial. These thoughts, along with certain external circumstances, create what are known as response biases.

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
