A professor of mathematics teaches at a catholic school and at a public school. He wants to knowwhether attending a catholic school leads to higher grades. He collected data from 7,430 studentsfrom both school's types. Considering this information, please answer the following questions:a) How can you interpret the OLS outcome on whether the child attended a catholic school(cathhs) is important to explain students' grade?SourceModelResidualTotalcathhslfamincSS143098.058521610.985motheducfatheduc664709.043dfmath12 Coefficient Std. err.17887.257387,421 70.28850367,429 89.47490151.623158 .41066691.447696 .1431147.0613988.7345401.832485. 055494black-5.226717hispan -1.221689asian3.28341female_consMS.3915981.3328612.4438741-1.066021 .195064916.72931 1.355485Number of obsF(8, 7421)Prob > FR-squaredAdj R-squaredRoot MSEt P>|t|3.95 0.0000.00010.1211.96 0.00015.00 0.000-13.350.000-3.67 0.0007.400.000-5.46 0.00012.34 0.000=.81813431.167151.6141811.7237009-5.99436-1.8741912.413291-1.44840314.07218===7,430254.480.00000.21530.21448.3838[95% conf. interval]2.4281821.728241.8548992.941269-4.459073-.56918654.153529-.68363819.38645

The number of awards earned by students at one high school is recorded. Predictors of the number of awards earned include the type of program in which the student was enrolled (e.g., vocational, general or academic) and the score on their final exam in math. Below is a description of the variables and their levels of measurement Variables Student ID - NOMINAL Math Scores - RATIO Total # of awards - DISCRETE Program Type - NOMINAL (categorical with three levels: (1)general, (2)academic, (3)vocational) Total Students= 200 Total Awards = 194 Total math scores = 10529 Program Type sum = 405 Summarize in words the frequency distribution for the program type variable.

Denny studied factors affecting cardiovascular reactivity to a postural change in a sample of healthy men and women. Change in systolic blood pressure (SBP) from supine to standing position was used as the measure of cardiac reactivity in a sample of 842 adults. Supine measurement of blood pressure was taken after participants had lain on an examination table for 15 minutes. Blood pressure was determined every 30 seconds using a Dinamap device for 2 minutes, and the measurements were averaged. Participants then stood up immediately, and additional measurements were made for another 2 minutes. Below is a table describing the characteristics of Denny’s sample: Which measures of dispersion, if any, are presented in this table (Ranges, SDs)? If age is normally distributed, approximately what percent of the sample would be younger than 50? If BMI is normally distributed, approximately what percent of the sample would have a BMI higher than 33.1?
