Do parents feel differently today than they did twenty years ago? Use the a 0.1 level of significance. Because npo (1-Po) 190.9 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho p = 0.49 versus H₁ P 0.49 (Type integers or decimals. Do not round.) Find the test statistic. zo (Round to two decimal places as needed.)
