This website includes the abortion statistics of the world and breaks the data down to the demographics of the United States. It also discusses the decisions to have an abortion and the use of contraceptives in the United States. This was an informative website and included detailed statistics conducted by the Alan Guttmacher

rejection of the null hypothesis when in reality the hypothesis is correct. The null hypothesis describes the population parameters that the data will represent if the predicted relationship does not exist. Alternative hypothesis describes the population that the sample data represents if the relationship does exist. Because the researcher is predicting that the film will change the attitude of the students toward the mentally ill I would think this is the null hypothesis. I say this because

means are not equal. Conclusion‚ at the .05 significance level‚ 5.24 F exceeds the F-critical value of 3.159. There is sufficient evidence to reject the Null hypothesis in favor of the alternative. The P-value is .00081399‚ the ANOVA P-value is significantly less than alpha‚ and therefore there is strong evidence to reject the null hypothesis. Using the inferences about individual treatment means is appropriate‚ when we look at the health of the patients. It is reasonable to believe that all the

Feedback: This level of significance‚ commonly set to α equal to 0.05‚ is used to set the cut-off as the maximum probability a researcher would use in order to reject a true null hypothesis.

1. The null hypothesis: There are no promising variables that seem to have a relationship with the amount of the prepaid cards The alternative hypothesis: There are variables that have a relationship to the amount stored on the prepaid card. To find out of if we are to accept or reject the null hypothesis we are first to determine the critical value‚ this was done by using the denominators (20)‚ and then aligning with the number of degrees of freedom (4) at the 0.05 significance level.

THE MONTHLY DEMAND FOR CHICKEN IN A RURAL VS AN URBAN AREA IN GUYANA A PROPOSAL INTRODUCTION The demand for chicken refers to the quantity of chicken demanded by households (in lbs) in the identified areas (one rural and one urban)‚ at the available prices within the specified areas. It must be noted at this point‚ that the true population in any given situation is never really known. As such samples are usually collected and estimated using econometric methods. The results are then used

Write the word or phrase that best completes each statement or answers the question. A hypothesis test is to be performed. Determine the null and alternative hypotheses. 1) A manufacturer claims that the mean amount of juice in its 16 ounce bottles is 16.1 ounces. A consumer advocacy group wants to perform a hypothesis test to determine whether the mean amount is actually less than this. Classify the hypothesis test as two-tailed‚ left-tailed‚ or right-tailed. 2) At one school‚ the average amount

months that has positive investment returns on AT&T are equal to months of negative returns. Therefore he sets a hypothesis; the null hypothesis H0 :ppositive = pnegative = 0.5 versus the alternative hypothesis Ha: not H0. The number of months that has the positive returns on AT&T is 32‚ and the number of months that has the negative returns is 22. In order to test the hypothesis‚ he should do chi-square test. First of all he calculates the expected value that has the positive and negative returns
