You are conducting a study to see if the probability of catching the flu this year is significantly less than 0.13. You use a significance level of α=0.002 H0:p=0.13 H1:p<0.13 You obtain a sample of size n=749 in which there are 84 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value...
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.64. Thus you are performing a left-tailed test. Your sample data produce the test statistic z=−1.104. Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the probability of catching the flu this year is significantly different from 0.39. You use a significance level of α=0.02 α=0.02 . H0:p=0.39 H0:p=0.39 H1:p≠0.39 H1:p≠0.39 You obtain a sample of size n=427 n=427 in which there are 190 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)...
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.16. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=−3.214. Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.79. With H :P < 0.79 you obtain a test statistic of z = - 3.061. Use a normal distribution calculator and the test statistic to find the P-value accurate to 4 decimal places. It may be left tailed, right-tailed, or 2-tailed. P-value =
You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.27. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=2.887z=2.887. Find the p-value accurate to 4 decimal places.
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.86. Thus you are performing a two-tailed test. Your sample data produce the test statistic z = − 1.725 . Find the p-value accurate to 4 decimal places. p-value =
You are conducting a study to see if the proportion of men over 50 who regularly have their prostate examined is significantly different from 0.84. Thus you are performing a two-tailed test. Your sample data produce the test statistic z=2.029 Find the p-value accurate to 4 decimal places. p-value =
please help! see all pics! 5. (1 pts) You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly less than 0.59. Thus you are performing a test statistic z -1.835. Find the p-value accurate to 4 decimal places. Label the standard normal curve and shade the appropriate area. -tailed test. Your sample data produce the p-value= 6. (6 pts) Test the claim that the proportion of people...
Suppose are running a study/poll about the probability of catching the flu this year. You randomly sample 65 people and find that 60 of them match the condition you are testing. Suppose you are have the following null and alternative hypotheses for a test you are running: H 0 : p = 0.95 H 0 : p = 0.95 H a : p < 0.95 H a : p < 0.95 Calculate the test statistic, rounded to 3 decimal places...
