Suppose that you are given two random variables x and y and you take measurements and obtain x1 = 2.3%, x2 = −7.6%, x3 = 0.1% and y1 = 60, y2 = 120, y3 = 80. Find the line of best fit y = α + βx. Calculate the correlation coefficient r and perform a left-tailed hypothesis test for r with significance level 10%. Based on this test, should we use this line to find the value of y when x = .5%?x y x2 y2 xy

- What is an experiment?arrow_forwardIn Hong Kong, some employers claim that they are willing to offer betterstarting salaries for those university graduates with a higher GPA. A study on Hong Kong university students was carried out. A simple random sample of 96 students who were admitted to Hong Kong universities between 2010 and 2013 was selected. Final cumulative GPA and starting salary (monthly salary in Hong Kong Dollars) of each participant were collected. A scatterplot of the two variables (gpa = final cumulative GPA; salary = starting salary) is shown below.arrow_forwardA random sample of 15 families representing three social classes has been observed for the frequency with which the parents administer physical punishment to the children over a period of a week.

- A researcher randomly sampled 30 graduates of an MBA program and recorded data about their starting salaries. Of primary interest to the researcher is whether starting salaries differ based on gender. The researcher performs a pooled-variance t-test of the mean salaries of the females (Population 1) andmales (Population 2) in the sample. Assume α = 0.10. What assumptions are necessary to conduct this hypothesis test? The samples were randomly and independently selected. Both populations of salaries (male and female) must have approximate normal distributions. The population variances are approximately equal.arrow_forwardAn HR manager in a company wants to know if there’s a difference in the amount of timeworkers in different departments spend chatting at the water cooler.
