When using a one sample Z procedure using Z scores to construct a confidence interval for a population proportion we need to check that the sample proportions are Normally distributed Which of the following best represent the condition s for Normality in this case A The sample size must be greater than or equal to 30 B The product of np and n 1 p must be at least 10 C The data must come from a simple random sample D The sample must be no more than 10 of the population Q4 5 points A 2022 survey found that 300 out of 400 young adults read at least 5 books during 2021 We want to construct a 92 percent confidence interval for the proportion of all young adults who read at least 5 books during 2021 Which of the following represents that interval A 300 1 7507 0 75 0 25 400 3 300 1 4051 0 75 0 25 400 0 75 1 7507 0 75 0 25 400 0 75 1 4051 0 75 0 25 400
