You wish to test the following claim (H.) at a significance level of a = 0.002. H.:p1 – P2 = 0 P2 > 0 You obtain a sample from the first population with 384 successes and 63 failures. You obtain a sample from the second population with 606 successes and 116 failures. 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 = %3D The p-value is... O less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null hypothesis accept the null hypothesis fail to reject the null hypothesis As such, the final conclusion is that...

i can come up with the correct answer to these two types of problems. I know I am just missing a small piece of it. hypothesist test for single population mean and single population proportion. need to figure out test statistic . and "p" value 2. 20% all college students volunteer their time. is the percentage of college student who are volunteers different for students receiving financial aid? of the 387 randomly selected students who receive financial aid, 58 of them volunteered their time. what can be concluded at the alpha 0.05 level of significance. Need to figure test statistic and "p" value.
In 1908, William Gosset published the article "The probable Error of a Mean" under the pseudonym of "Student". He included the data listed below for two different types of corn seed that were used on ad jacent plots of land. The listed values are the yields of head corn in pounds per acre. Use a 0.10 significance level to test the claim that the mean difference in yield between the two types of seed is 0.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"

A random sample of size 21 was taken from a normal population. The sample average was 9.87 and the sample SD was 1.17. At the significance level of 10%, what test should you use for testing whether the population mean equals 9.7? One sample z-test for the population mean. two sample z-test for the population means. One sample z-test for proportions. two sample z-test for proportions. one sample t-test for the population mean. 3 26
