Chapter 15, Problem 15.55AC

The data show the test results from students in two classrooms, one integrated and one not. There are two sets of test scores, a pre-test and a post-test for both groups. First, calculate a measure of change in the test scores for students in both groups. Then, use the resulting measure of change to compare both groups on the measure of change from the pre-test to the post-test. When finished, write a short summary of what you found, including: Group 1 mean Group 2 mean Ho and H1 t-observed t-critical

Please do help me with this one. It doesn't need calculation but understanding only. Classify each variable as a discrete or continuous variable. *The weight of baggage on an airplane. *Heights of basketball players on a local high school team. *The highest wind speed of a typhoon. *The number of pages in a statistics book. *The amount of money a person spends per year for online purchases.   Please do help me.

Classification is most closely associated with diagnostic analytics. T/F

a digital blood pressure cuff is often used to measure blood pressure patients who check their blood pressure at home. readings are recorded as mmHg (millimeters of mercury). A normal blood pressure is generally any reading below 120/80 mmHg. Identify the variable.

Draw a histogram for the data. Use a class width of 15. Be sure to include the screenshot of Excel of your answers and formulas/command that you use.

@ The scatter plot shows the relationship between time, in 5-year intervals, and the population of a town. Explain why time was used as the independent variable. Time Population

Determine whether the value is from a discrete or continuous data set.Number of bacteria in a petri dish is 12,120Is the value from a discrete or continuous data set?

Identify what is qualitative or quantitative variable. If it is quantitative variables, further categorize them into either the discrete or continuous.  Sex  Blood Type Blood Glucose Level  Household size  Region
