Solutions to Questions on Hypothesis Testing and Regression 1. A mileage test is conducted for a new car model‚ the “Pizzazz.” Thirty (n=30) random selected Pizzazzes are driven for a month and the mileage is carefully measured in each. The mean mileage for the sample is 28.6 miles per gallon (mpg) and the sample standard deviation is 2.2 mpg. Estimate a 95% confidence interval for the mean mpg in the entire population of Pizzazzes (you might need to round your answer a little bit to agree with mine)

ECON 103‚ Lecture 16: Heteroskedasticity (continued) Maria Casanova March 05 (version 1) Maria Casanova Lecture 16 1. Introduction Recall the definition of heteroskedasticity we saw last week: When the variance of Y depends on the value of X ‚ we say that there is heteroskedasticity‚ or that the error term u is heteroskedastic: Var (Yi |Xi ) = Var (ui |Xi ) = f (Xi ) = σi2 The next slide shows an example of heteroskedasticity where the variance of Y is higher for low values

Poisson Regression This page shows an example of poisson regression analysis with footnotes explaining the output. The data collected were academic information on 316 students. The response variable is days absent during the school year (daysabs)‚ from which we explore its relationship with math standardized tests score (mathnce)‚ language standardized tests score (langnce) and gender . As assumed for a Poisson model our response variable is a count variable and each subject has the same length

involve multiple areas in the use of DC‚ while limits of time‚ more participants surveyed with responses and larger sample size‚ high cost‚ unequal age groups of participants ‚ the use of sophisticated statistical techniques (such as Micro fit or Stata to analysed primary data effectively) and lack of detail information on the research questions for the participants could not make all areas be investigated in detail. Thus‚ the outcome of the results might be significantly different from the present

Math 143 – ANOVA Analysis of Variance (ANOVA) 1 Recall‚ when we wanted to compare two population means‚ we used the 2-sample t procedures . Now let’s expand this to compare k ≥ 3 population means. As with the t-test‚ we can graphically get an idea of what is going on by looking at side-by-side boxplots. (See Example 12.3‚ p. 748‚ along with Figure 12.3‚ p. 749.) 1 Basic ANOVA concepts 1.1 The Setting Generally‚ we are considering a quantitative response variable as it relates to one or
