Will the critical value approach and the p-value approach return the same conclusion for a hypothesis test?
When conducting a hypothesis test (or test of significance), select all the true statement. assume the alternative hypothesis is true. significance level is selected before collecting data. None of these (can be more than one answer) Select the correct answer for the blank of each of the following statements.(i) A smaller significance level makes it (choose one: more difficult, easier) to reject the null hypothesis.(ii) The p-value of a two-tail (or two-side) test is (choose one: twice(double), half of, same as) the p-value of a one-tail (or one-side) test if everything else stays the same.(iii) It is (choose one: possible, impossible) to make both type I error and type II error in one hypothesis test at the same time.(iv) Statistical significance (choose one: implies, does not imply) practical significance.
In a recent study it was found that of 450 physicians polled 162 were women and of 530 nurses polled 445 were women. Test the claim using the traditional method of hypothesis testing that the proportion of nurses who are women is greater than the proportion of physicians who are women. Assume a significance level of 0.01 Let p1=the proportion of nurses who are women Let p2=the proportion of physicians who are women a) What is the claim? p1 ">, < or =" p2 b) What is the Null Hypothesis? p1 ">, < or =" p2 c) What is the Alternative Hypothesis? p1 ">, < or =" p2 d) Which type of test will be used?

Suppose 300 subjects are treated with a drug that is used to treat pain and 78 of them developed nausea. Use a 0.05 significance level to test the claim that more than 204% of users develop nausea.The test statistic for this hypothesis test is .(Round to two decimal places as needed.)The P-value for this hypothesis test is
I need to turn this into a hypothesis test using a Ti84 As a dog owner I became curious as to the reason, why people choose to own a dog. I claim that more women choose to own a dog mainly for companionship than women who choose to have a large dog mainly for companionship. Do the data provide sufficient evidence to conclude that the proportion of women who prefer small dogs for companionship greater than the proportion of women who prefer large dogs for companionship? On Sunday, I will stand outside of my local Petco and survey women who are entering the store. I will ask if they own a dog, the main reason that they acquired a dog whether it was for protection or companionship and the size of their dog. I will collect this data in my notebook. I will not collect data from people exiting the store to ensure that I do not survey the same person more than once. I will acquire 30 samples of women who own small dogs and 30 women who own large dogs. I will not include women under the…

Suppose 231 subjects are treated with a drug that is used to treat pain and 55 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is Identify the P-value for this hypothesis test. The P-value for this hypothesis test is
Do the needs of patients in the emergency room differ for those who come by car vs. those by ambulance? Of the randomly selected emergency room patients who came by car 51 had an injury, 40 were sick, 31 had heart problems and 61 had other needs. Of the randomly selected emergency room patients who came by ambulance 45 had an injury, 30 were sick, 55 had heart problems and 38 had other needs. Conduct the appropriate hypothesis test using an a = 0.10 level of significance. a. What is the correct statistical test to use? O Paired t-test O Homogeneity Goodness-of-Fit O Independence b. What are the null and alternative hypotheses? Ho: O Means of transportation to the emergency room and emergency room needs are independent. Means of transportation to the emergency room and emergency room needs are dependent. The distribution of emergency room needs for patients who come by car is the same as it is for patients who come by ambulance. The distribution of emergency room needs for patients who…
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 285 people over the age of 55, 76 dream in black and white, and among 287 people under the age of 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 H: P1> P2 O B. Ho: P1 = P2 OC.
