Suppose you are interested in constructing a 95% confidence interval to determine the true proportion of residents in Kern County that are planning on voting for the republican candidate in the next presidential election. If you want to make sure that you are within 0.15 of the actual proportion, how many residents would you need to include in your sample? Reminder: It’s impossible to survey a fraction of a person

A survey was done of residents/households in Kern County, and it found that out of all Kern County households, 85.4% of them have a computer. Suppose you are hired to randomly sample 100 Kern County households and determine whether or not they have a computer. Use this data to answer the following question.  What is the probability that between 89% and 93% of the households that you survey will have a computer?   Make sure to type in your final answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was 0.12345 then you would type in 0.123.

Some believe that Captain America can run the fastest mile of any person alive. In order to test this theory, Captain America decided to run the mile multiple times and record how long it took him (in seconds) to run each one. He decided to attempt running the mile 40 times and determine his average mile time. Let’s assume his true mean mile time was 138 seconds with a standard deviation of 16 seconds. Use this information to find the following probability.  What is the probability that his average mile time would be between 136 and 141 seconds?   Make sure to round your final answer to 3 decimal places. For example, if you thought the answer was 0.123456 then you would type in 0.123.
