Q7

This is from a dataset of 420 CA school districts.

We estimate the relationship between the student-teacher ratio (X1=STR) and test scores (Y=TestScore), controlling for the percentage of English learners in the classroom (X2=PctEL):

TestScore=686.0-1.10*STR-0.65*PctEL

The standard error of beta0hat is 8.7. The standard error of beta1hat is 0.43. The standard error of beta2hat is 0.31.

Test the statistical significance of STR using alpha=0.05.

What is the lower bound of your 95% confidence interval? Round to two decimal places.

In this set of questions, we utilize the dataset from “Revisiting the Relationship between Competition and Price Discrimination” written by Chandra and Lederman (2018) to look at some interesting questions and help you gain some knowledge in the airline industry and learn some econometric methods. The Herfindahl index (also known as Herfindahl–Hirschman Index, or herf in this dataset) is a measure of the size of firms in relation to the industry and an indicator of the amount of competition among...

A high school guidance counselor is interested in the relationship between proximity to school and participation in extracurricular activities. He collects the data on distance from home to school (in miles) and number of clubs joined for a sample of 10 juniors. Using the following data, compute a Pearson’s correlation coefficient and indicate whether the correlation is significant. State your null and alternative hypothesis and show your work step by step. Make sure interpret your finding (Use .05 significance level)....

In a study of the relationship between family size and school performance in junior high school, 25 children in “only child ” families had an average GPA (grade point average) of 2.82 with a standard deviation of 0.34, and 20 first-born children in two-child families had an average GPA of 2.96 with a standard deviation of 0.38. At the 0.05 level of significance, is the difference between these means significant? 1. You must state the null and alternative hypotheses. 2....

Motivated by findings from California that school districts with lower student-teacher ratios have higher average test scores, administrators in New York City recently reviewed the relationship between school- level student-teacher ratios and average test scores within their population of elementary schools. Data for fifth-grade test scores (reading and math) from 1,575 elementary schools yield Y ̄ = 631.7 and sY = 17.8 a) Construct a 95% confidence interval for the mean test score in the population (i.e., of schools in...

Suppose we want to estimate the average weight of children in a particular school district. The district contains 15 elementary schools, 10 middle schools, and 2 high schools. For each of the following approaches, select the best description of the sampling design, and identify whether the sampling scheme ensures that the probability of being included is necessarily the same for every student. A. List all the students in the school district. Average the weights of every 50th student on the...

1:) The dataset shows 15 observations of the relationship between cricket chirps (measured in chirps per second) and outside ground temperature (in Fahrenheit). A. Create a scatterplot by putting chirps on the vertical axis and temperature on the horizontal axis. Be sure to properly label the scatterplot with a title, axes titles, and the proper units of the variables. B. Estimate the following relationship: ?h????=?0+?1???????????(Chirps) ̂=b_0+b_1 Temperature. C. Interpret the slope in the context of the problem. D. Interpret the...
