I have a probabilty and sample spaces geometry question. The table below shows the number different colored buttons in a bag. A student puts her hand in the bag andrandomly takes out one button. Each of the buttons is the same size and shape, so they are equally likely to beselected. Apply mathematics to determine the probability that she will take out a green button. Express theprobability as a percentage.P (green) =%ColorredorangeyellowgreenblueNumber of buttons9121478

and performance tasks. Perform the test of hypothesis on the following scenarios. than Php 5,000.00 per day. The CEO of a large supermarket chain in the region is claiming to be paying its contractual higher than the minimum daily wage rate of Php 500.00 1o check on this claim, a labour union leader obtained a random sample of 144 contractuai employees from this supermarket chain. The survey of their daily wage earnings resulted to an average wage of Php 510.00 per day with standard deviation of Php 100.00. The daily wage of the region is assumed to follow a distribution with unknown population variance. Perform a test of hypothesis at 5% level of significance to help the labour union leader make an empirical based conclusion on the CEO's claim. General As a do the for works 1.

Five big personality tests are standardized so that the average score is 100 for the entire group of people who take the test each year. However, if we selected a group of 40 people who took the test and computed their average test score, we probably would not get 100. What statistical concept explains the difference between the group mean and the mean for the entire group? Lütfen birini seçin: A. descriptive error B. statistical error C. sampling error D. inferential error
Do people in different political parties use similar modes of transportation? Researchers ask a group of people about how they get to work. They also group the people by their political party. They want to determine if the distribution of transportation is the same for democrats and republicans. The data are recorded in the contingency table below, and a chi-square Homogeneity Test at the 1% significance level is performed. Car Public Transit Walk Row Total Democrats 21 16 6 43 Republicans 8 25 16 49 Column Total 29 41 22 92 Select the correct null and alternative hypotheses for this test.

A randomized experiment was done by randomly assigning each participant either to walk for half an hour three times a week or to sit quietly reading a book for half an hour three times a week. At the end of a year the change in participants' blood pressure over the year was measured, and the change was compared for the two groups. "This is a randomized experiment rather than an observational study because: * A. Blood pressure was measured at the beginning and end of the study. B. A random sample of participants was used. C.

John wants to open a learning center for high school students in his community. John wants to compare the average time area high school students spend studying per week with the regional average, 20.5 hours. John surveys 25 randomly selected local high school students, asking how much time they spend studying in a typical week. Graphs of his sample data show no strong skewness or outliers. Choose the correct inference procedure that John should use to test if the mean weekly study time from his sample differs from 20.5 hours: one-sample, two-sided z-test for a proportion one-sample, right-tailed t-test for a mean one-sample, left-tailed t-test for a mean one-sample, two-sided t-test for a mean
