Suppose we want to test the null hypothesis H0 : p1 - p2 = 0 against the alternative hypothesis H1 : p1 - p2 < 0 at the 2.5% level of significance. Suppose also that ^p1=0.8p^1=0.8, n1=500n1=500, ^p2=0.75p^2=0.75, n2=400n2=400. What is the p-value for this test? Select one: a. 0.0462 b. 0.0367 c. 0.9633 d. 0.025

When conducting an ANOVA on sbp and genhelth, the p-value is 0.02. Therefore we conclude reject the null hypothesis at 1% level, mean sbp different for all categories of genhelth no evidence to reject the null hypothesis of equal means reject the null hypothesis at 5% level, mean sbp different for all categories of genhelth reject the null hypothesis at 5% level, mean sbp different for at least one category of genhelth Formula sheet.docx Ef 88 13°C A 0 4, N Type here to search O

If we have a sample size of 100 from a population of rope with sample mean breaking strenfgth of 1040 pounds with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength exceeds 1000 pounds, then what is the TYPE 1 ERROR

A teacher has a large container of blue, red, and green beads. She reports to the students that the proportion of blue beads in the container is 0.30. The students feel the proportion of blue beads is lower than 0.30. A student randomly selects 60 beads and finds that 12 of the beads are blue. The P-value for the test of the hypotheses, H_{0} / p = 0.30 and H_{a} / p < 0.30 , is 0.045. What is the correct interpretation of this value? There is a 4.5% chance the proportion of blue beads in the container is 0.3. Assuming the true proportion of blue beads in the container is 0.30, there is a 4.5% probability that the null hypothesis is true. Assuming the true proportion of blue beads in the container is 0.30, there is a 4.5% probability that the sample proportion would be 0.20 or less by chance alone. Assuming the true proportion of blue beads in the container is less than 0.30, there is a 4.5% probability that the sample proportion would be 0.20 or less by chance alone.
Suppose we are testing the null hypothesis H_0 : \mu = 32H0:μ=32 and the alternative hypothesis H_a : \mu \ne 32Ha:μ=32, for a normal population with population standard deviation of \sigma =σ= 3.5. A random sample of sixteen observations are drawn from the population, and we find the sample mean of these observations is \overline{x} =x= 30.5. Compute the P-value for this test. Give your answer to four decimal places.
