You are conducting a study to see if the proportion of men over the age of 50 who regularly have their prostate examined is significantly less than 0.38. A random sample of 707 men over the age of 50 found that 209 have their prostate regularly examined. Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer ?

Life on Other Planets Forty-five percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 110 randomly selected individuals and found 66 believed that there is life on other planets. At α=0.05, is there sufficient evidence to conclude that the percentage differs from 45? Use the P-value method with a graphing calculator. State the hypotheses and identify the claim with the correct hypothesis. H0 : p=0.45 ▼not claim H1 : p≠0.45 ▼claim This hypothesis test is a ▼two-tailed test.   Find the P-value. Round the answer to four decimal places.   P-value = ___________________

practice question #9. A sample of 340 randomly selected adult Americans were asked this question: “Do you use a remote start for your vehicle during the Winter?” 117 answered “yes.” Based on this, is it reasonable to assume that more than 33% of adult Americans use a remote start during the Winter? Set up the relevant hypotheses, show the sample is appropriate for this test, calculate a test statistic and P-value, decide whether or not to reject the null hypothesis, and put your conclusion in context of the scenario. Round P-value to 4 decimal places and test statistic to 2 decimal places. Use ∝= .05. Hypotheses: Address appropriateness of size: Value of test statistic: ________________________________ P-value: ________________________________ State your conclusion in the context of the problem.

Suppose are running a study/poll about the proportion of men over 50 who regularly have their prostate examined. You randomly sample 81 people and find that 71 of them match the condition you are testing.Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.87Ha:p≠0.87Calculate the test statistic, rounded to 3 decimal places.

Suppose are running a study/poll about the accuracy rate for fingerprint identification. You randomly sample 75 people and find that 62 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.78H0:p=0.78Ha:p≠0.78Ha:p≠0.78 Calculate the test statistic, rounded to 3 decimal places. z=

You are conducting a study to see if the proportion of men over the age of 50 who regularly have their prostate examined is significantly less than 0.33. A random sample of 737 men over the age of 50 found that 206 have their prostate regularly examined. Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: p Test Statistic = OB H₁: p Based on the hypotheses, find the following: Critical-value= OB 0.33 0.33 Or

You are conducting a study to see if the proportion of men over the age of 50 who regularly have their prostate examined is significantly less than 0.36. A random sample of 707 men over the age of 50 found that 198 have their prostate regularly examined. Do the sample data provide convincing evidence to support the claim? Test the relevant hypotheses using a 10% level of significance. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer v? v H1: Select an answer ? v Based on the hypotheses, find the following: Test Statistic = Critical-value= Shade the sampling distribution curve with the correct critical value(s) and shade the critical regions. The arrows can only be dragged to z-scores that are accurate to 1 place after the decimal point (these values correspond to the tick marks on the horizontal axis). Select from the drop down menu to shade to the left, to the right,…

A December 2017 Gallup Poll reported that 43% of Americans use the internet for an hour or more each day. You suspect that a greater proportion of students at your school use the internet that much. You take a random sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school has more than 600 students. You will test the hypotheses H, : p = 0.43, H,:p>0.43 , where p= the true proportion of students at your school who use the internet for an hour or more each day. Which of the following gives the correct test statistic for this test? 0.43 - 0.6 Z = (0.6)(0.4) 60 0.43-0.6 (0.6)(0.4) 600 0.6-0.43 (0.6)(0.4) 60 0.6 - 0.43 (0.43)(0.57) 60 36 - 60 (36)(24) 60

The test statistic for this hypothesis? The p value?
