If the conclusion in a hypothesis test is to fail to reject H0H0, we can conclude that there is strong evidence that the null hypothesis is true.
Suppose that you want to perform a hypothesis test for a population mean, μ. a. Express the null hypothesis both in words and in symbolic form. b. Express each of the three possible alternative hypotheses in words and in symbolic form.
A random sample of upperclassmen (juniors, seniors) and a random sample of lowerclassmen (freshman, sophomores) were asked if they use study groups for any of their classes. 157 (63%) out of 250 upperclassmen and 232 (58%) out of 400 lowerclassmen reported using study groups. Suppose all the assumptions for conducting the hypothesis test are met.
Which set of numbers would correspond to a hypothesis test with the greatest power? Cohen's d = 0.6 & n = 500 O Cohen's d = 0.6 & n = 50 O Cohen's d = 0.5 & n = 50 O Cohen's d = 0.5 & n = 500
According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value
