You may need to use the appropriate appendix table or technology to answer this question. The population proportion is 0.40. What is the probability that a sample proportion will be within ±0.04 of the population proportion for each of the following sample sizes? (Round your answers to 4 decimal places.) (a) n = 100 (b) n = 200 (c) n = 500 (d) n = 1,000 (e) What is the advantage of a larger sample size? We can guarantee p will be within ±0.04 of the population proportion p. There is a higher probability σp will be within ±0.04 of the population standard deviation. As sample size increases, E(p) approaches p. There is a higher probability p will be within ±0.04 of the population proportion p

A report states that adults 18- to 24- years-old send and
receive 128 texts every day. Suppose we take a sample of 25- to 34-
year-olds to see if their mean number of daily texts differs from
the mean for 18- to 24- year-olds.
(a)
State the null and alternative hypotheses we should use to test
whether the population mean daily number of texts for...

A research center has conducted extensive research on social
media usage. One finding was that 71% of adults aged 18 to 24 use
Snapchat. Another finding was that 48% of those aged 18 to 24 use
Twitter. Assume the sample size associated with both findings is
400.
