Eggs produced by a certain breed of hen have a mean weight of 65000 milligrams. A large egg supplier samples 25,000 of this breed's eggs from their stock. This sample of eggs is found to have a mean weight of 64900 milligrams. Although the difference in means is fairly small, the results are determined to be statistically significant. The most likely explanation is
a. |
that the sample size is very large. |
|
b. |
that the mean of 65000 milligrams is very large. |
|
c. |
that the hens are severely malnourished. |
|
d. |
all of the above. |
The most likely explanation is that the sample size is very large.
Hence option a is correct.
This is because with large sample you are virtually certain to see statistically significant result. With large samples you are less likely to see result that reflects randomness that is the likelihood of obtaining statistical significant result increases as sample size increases.

The weight of the eggs produced by a certain breed of hen is normally distributed with mean 66.6 grams (g) and standard deviation 4.6 g. If cartons of such eggs can be considered to be SRSs of size 12 from the population of all eggs, what is the probability that the weight of a carton falls between 775 g and 825 g? (Round your answer to four decimal places.) =
1) Suppose cattle in a large herd have a mean weight of 1169lbs and a variance of 17,161. What is the probability that the mean weight of the sample of cows would differ from the population mean by greater than 12lbs if 145 cows are sampled at random from the herd? Round your answer to four decimal places. 2) The mean lifetime of a tire is 36 months with a variance of 49. If 126 tires are sampled, what is...
Can Dogs Understand Human Cues? EXPLORATION Dogs have been domesticated for about 14,000 years. In that time, have they been able to develop an understanding of human gestures such as pointing or glancing? How about simi lar nonhuman cues? Researchers Udell, Giglio, and Wynne tested a small number of dogs in order to answer these questions. In this exploration, we wll first see whether dogs can understand human gestures as well as nonhuman gestures. To test this, the researchers positioned...

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
