What is the p-value if, in a two-tail hypothesis test, ZSTAT = +1.96? Click here to view page 1 of the Normal table. Click here to view page 2 of the Normal table. ... p-value = (Round to four decimal places as needed.)
Suppose you conduct a hypothesis test based on a sample where the sample size is n = 50, and arrive at a p-value of 0.08. You then refer back to your notes and discover that you made a careless mistake, the sample size should have been n = 500. Will your p-value increase, decrease, or stay the same? stay the same increase decrease Answer not here

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 210 pet owners and discovered that 66 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a=0.01 level of significance. Because npo (1-Po) = 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho versus H₁ (Type integers or decimals. Do not round.) Find the test statistic, Zo Zo= (Round to two decimal places as needed.) Find the P-value. 5% of the population size, and the sample the requirements for testing the hypothesis P-value= (Round to three decimal places as needed.) Does the veterinarian have a right to be skeptical? OA. The veterinarian has a right to be skeptical. There is sufficient evidence to conclude that the true proportion of pet owners who talk to their pets on the telephone is less than 33%. OB.…
Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 74 people and find that 41 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho:p = 0.53 Ha:p + 0.53 Calculate the test statistic, rounded to 3 decimal places = Z

Assume that a simple random sample has been selected from a normally distributed population. Identify the null hypothesis, alternative hypothesis, test statistic, P-value (or range of p-values), conclusion about the null hypothesis, and final conclusion that addresses the original claim. 1) Test the claim that the mean age of the graduate school population in one city is less than 33 years. Sample data are summarized as n 67, x = 42.4 years, and s = 31.5 years. Use a significance level of a = 0.10.
What is the p-value if, in a two-tail hypothesis test, ZSTAT=+1.45? p-value= (Round to four decimal places as needed.)
The dataset "nurses" is a random sample of 1,000 cases from “Health Care Provider Credential Data” from Washington State Open Data Portal. In the sample, there are 418 CNA's and 278 of the CNA's have expired credentials. Use the statistics from the nurses dataset to answer the following question: "With 90% confidence, what percent of all CNA's on Washington State's healthcare provider list are expired?"
