Question
I need help finding the critical value.
In a survey, 33% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so she randomly selected 200 pet owners and discovered that 65 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a=0.1 level of significance. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Because npo (1-Po) = 44.2 5% of the population size, and the sample is given to be random, 10; the sample size is less than the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho Р 0.33 versus H₁: p 0.33 (Type integers or decimals. Do not round.) Determine the test statistic, Zo- Zo = -0.15 (Round to two decimal places as needed.) Determine the critical value(s). Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) OA. ±2a/2= ± OB. Za =
