From the 2010 US Census, we learn that 71.8% of the residents of Missouri are 21 years old or over. If we take random samples of size n = 200 and calculate the proportion of the sample that is 21 years old or over, describe the shape, state the mean, and standard error of the distribution of sample proportions. (Make sure you justify your answer.)

Based on data from a statistical abstract, only about 14% of senior citizens (65 years old or older) get the flu each year. However, about 23% of the people under 65 years old get the flu each year. In the general population, there are 13.5% senior citizens (65 years old or older). (Round your answers to three decimal places.)

Census ~ In 2020, Pew Research conducted a poll to examine how likely a person was to participate in the 2020 US Census based on their age. In a random sample of US adults aged 50 years or older, 85.63% said they were likely to participate in the Census. The estimated standard error of the sample proportion is 0.0064. A normal distribution can be used to model the sampling distribution of sample proportion. The researchers wish to construct a 95%...

Census ~ In 2020, Pew Research conducted a poll to examine how likely a person was to participate in the 2020 US Census based on their age. In a random sample of US adults aged 18 - 49 years old, 67.45% said they were likely to participate in the Census. The estimated standard error of the sample proportion is 0.0148. A normal distribution can be used to model the sampling distribution of sample proportion. The researchers wish to construct a...

As we learn more about the people who have come before us, we have to be careful not judge them through the lens of the present, or assume they could or should have acted as you or I today would act. Remember, "The past is a foreign country: they do things differently there." In that spirit, identify an American belief or practice we generally understand or accept today as "normal" that, one hundred years from now, future generations might be...

Suppose the age that children learn to walk is normally distributed with mean 11 months and standard deviation 1.1 month. 14 randomly selected people were asked what age they learned to walk. Round all answers to 4 decimal places where possible. What is the probability that one randomly selected person learned to walk when the person was between 9.5 and 12.5 months old? For the 14 people, find the probability that the average age that they learned to walk is...
