Let the height data (105)represent sample. Use an appropriate statistical test to check whether the population mean is different from 170 cm.Use α = 0.05.Also, write a substantive conclusion and explanation. Use an appropriate graph to check if data is normally distributed. Do it in R commander.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Types of restaurants (fast food, organic food, sea food, etc.) Choose the correct answer below. A. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point. O B. The nominal level of measurement is most appropriate because the data cannot be ordered. OC. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. O D. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point.
The four levels of measurement scale are Nominal, Ordinal, Interval and Ratio. What can be computed with each type (Frequency, Median, Mean, Standard Deviation, Standard error, Ratio, Coefficient of variation)?
INSTRUCTION: Provide Descriptive Statistics using the Data Analysis in Excel for the “Systolic Blood Pressure” set of data. Copy the result of the Descriptive Statistics in a short bond paper. Based on the dataset, what measure of central tendency (Mean, Median or Mode) should be used and explained? Interpret also the values in relation to Skewness and Kurtosis. NOTE: Place your answers in Microsoft Word Document (size: 8.5” x 11”).
3. During each of four experiments on the use of carbon tetrachloride as a worm killer, ten rats were infested with larvae (Armitage 1983). Eight days later, five rats were treated with carbon tetrachloride; the other five were kept as controls. After two more days, all the rats were killed and the number of worms were killed. The table below gives the counts of worms for the four control groups. Significant differences, although not expected, might be attributable to changes in experimental conditions. A finding of significant differences could result in more carefully controlled experimentation and thus greater precision in later work. Use both graphical techniques (e.g. boxplots) and the F test to test whether there are significant differences among the four groups.
