Review 4 Question 17 Consider the following: Suppose cattle in a large herd have a mean weight of 1212 lbs and a standard deviation of 77. PROBABILITY What is the probability that the mean weight of the sample steers would be greater than 1220 lbs if 62 steers are sampled at random from the herd? Answer: (Round your answer to 4 decimal places) (Review 4 Q17)

Solution

Null Hypothesis : H0 = 1220

Alternative Hypothesis : Ha > 1220

z= (1220 - 1212) / (77/sqrt(62))

= 0.82

Therefore ,

Probability = 0.7939 Answer
