A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. O State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H: 0 O0 O20 O=0 ?
In hypothesis testing, O if the test statistic is negative, this means the sample statistic is larger than the claimed population parameter. we call the initial claim being tested about the population an alternative hypothesis. it is not necessary to know the population size in order to compute the test statistic. the "P" in P-value stands for "personal." results that are statistically significant will always be practically important (or practically significant).
A political scientist believes that affiliation to a political party either Deomcrat or Republican is independent of whether an individual has a college degree or not now have a degree. A random sample of 100 individuals is taken with the results provided in the joint frequencey table below. Test the hypothesis at the 0.05 level and make sure to show your work. Dem Rep college 30 20 no college 20 30
Test the claim that the mean GPA of night students is larger than 2.3 at the .025 significance level. The null and alternative hypothesis would be: Но : р — 2.3 Но:н — 2.3 Но:р %3D 0.575 Но: д —— 2.3 Но:р %3D 0.575 Но:р 3 0.575 H:р + 2.3 Hi:p 2.3 Н:р#0.575 H:р> 0.575 The test is: left-tailed right-tailed two-tailed Based on a sample of 65 people, the sample mean GPA was 2.34 with a standard deviation of 0.06 The test statistic is: (to 2 decimals) The critical value is: (to 2 decimals) Based on this we: O Fail to reject the null hypothesis O Reject the null hypothesis
The smaller the P-value, the ______ support for the alternate hypothesis -More -Less
A researcher carried out a two-tailed hypothesis test. Which of the following z-scores would result in the weakest evidence against the null hypothesis? O 1.10 -0.20 O-2.60 3.0
Let p be the propotion of seniors who will play bingo. Based on a random sample of 175 seniors, 103 of them have said that they will play bingo. Using this data, test the null hypothesis that p=.5 versus the alternative that p>.5 at the alpha = .1 level. What is the p-value and conclusion of this test? Should you reject or fail to reject the hypothesis?
In hypothesis testing, O if the P-value is 0.01, we should conclude there is a 1% chance the null hypothesis is false. O neither the test statistic nor the P-value can ever be negative. O we always begin the hypothesis test by assuming the null hypothesis is true. O if the P-value is 0.99, we should conclude that the null hypothesis is true. O results that are statistically significant will always be practically important (or practically significant).
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 68%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H, and the alternative hypothesis H that we would use for this test. H: 0 O
Someone claims the average high school GPA among incoming Berkeley freshmen is 3.9. A simple random sample of 150 freshmen is taken, however, and the average high school GPA in the sample is 3.5, with an SD of 0.5. Calculate the one-sample z test statistic based on this data, for the null hypothesis that the average in the population really is 3.9. a. -0.8 b. -10 c. 2.5
