Fаirfаx City оfficiаls decided tо inquire abоut their citizens' interest in mowing the lawn. Specifically they surveyed a random sample of 256 city residents who own a property with grass on it and posed the question, "Do you usually mow your lawn or do you hire a service to do it for you?" Of those surveyed 186 answered that they usually mow their lawn. A past survey of the entire city informed the officials that 65.1% of city residents who own a property with grass mow their own lawn. If the officials decide to take a second sample of 256 Fairfax City residents, compare the sample statistic obtained from this second sample with the one obtained from the first sample above (in problem 4).
Use the fоllоwing tо аnswer the next two questions. An experiment wаs conducted to exаmine the effect of "recency bias" on children. "Recency bias" is when children are just learning to speak, they are likely to mimic what they just heard. For example, when asked “Do you want cake or broccoli?”, a child might answer broccoli just because it was the last option presented. The experiment was developed around two-year-old children who were asked to choose between two options. In the experiment, each binary-choice question included pictures of the two options, and children answered by pointing at a picture. The researchers tested to see if the second option is more likely to be picked than the first, which means the proportion of times the second option is chosen is greater than 0.5. In the experiment with pictures, the toddlers picked the second choice 275 times out of 480 trials which is about 0.573. The p-value was found to be 0.002. Interpret the p-value of 0.002.
