Calculations for a set of variables

Open the class survey results that were entered into the MINITAB worksheet.

We want to calculate the mean for the 10 rolls of the die for each student in the class. Label the column next to die10 in the Worksheet with the word mean. Pull up Calc > Row Statistics and select the radio-button corresponding to Mean. For Input variables: enter all 10 rows of the die data. Go to the Store result in: and select the mean column. Click OK and the mean for each observation will show up in the Worksheet.

We also want to calculate the median for the 10 rolls of the die. Label the next column in the Worksheet with the word median. Repeat the above steps but select the radio-button that corresponds to Median and in the Store results in: text area, place the median column.

Calculating Descriptive Statistics

Calculate descriptive statistics for the mean and median columns that where created above. Pull up Stat > Basic Statistics > Display Descriptive Statistics and set Variables: to mean and median. The output will show up in your Session Window. Print this information.

Calculating Confidence Intervals for one Variable

Open the class survey results that were entered into the MINITAB worksheet.

We are interested in calculating a 95% confidence interval for the hours of sleep a student gets. Pull up Stat > Basic Statistics > 1-Sample t and set Samples in columns: to Sleep. Click the OK button and the results will appear in your Session Window.

We are also interested in the same analysis with a 99% confidence interval. Use the same steps except select the Options button and change the Confidence level: to 99.

...the written application of operation. It teaches students to think clearly, reason well and strategize effectively. Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance.

Lab6: Enzymes
Purpose: The purpose of this lab is to test for enzyme activity, look at enzyme specificity, and how temperature affects enzyme activity.
Hypothesis: I believe that the room temperature activity will produce the most activity.
Materials: 3% hydrogen peroxide, a household blender, potatoes (3 medium size potatoes, that are peeled and quartered), tap water, 8 test tubes, 8 transfer pipets, sugar packets, salt, a...

Part A
1. Run your model. Compare the queue statistics of the 3 processes with those obtained for Part C in the previous Lab. How have they changed and what conclusions can you draw? (Note the sums of all capacities for both cases are equivalent – 12 in each).
The queue time and number statistics for the Air Jordan Logo operators and the Air Max Logo Operators were relatively close. The average queue...

THEORY:
Statistical variation and measurement uncertainty are unavoidable. A theory is consistent if the measurement is 2m +/- 1m. Uncertainty rises from statistical variation, measurement precision, or systematic error.
EXPERIMENTAL OVERVIEW:
Part 1. Coin Toss: Statistical Variation:
Sixteen coins were tossed nine times and the...
