#5.A survey organization takes a simple random sample of 625 households from a city of 80,000 households. On the average, there are 2.3 people per sampled household, and the SD is 1.75. Circle TRUE or FALSE for each statement, and include a sentence to explain your answer. (Both must be correct to receive full credit.) Show how you get the 95% confidence. (a) TRUE or FALSE: If we use the sample average to estimate the population average, the estimate is likely to be off by about 0.07 people. Explanation: (b) TRUE or FALSE: A 95%-confidence interval for the average household size in the sample is 2.16 people to 2.44 people. Explanation: (c) TRUE or FALSE: 95% of the households in the city contain between 2.16 and 2.44 people. Explanation:
