STATISTICS - Lab #6 Statistical Concepts: Data Simulation Discrete Probability Distribution Confidence Intervals 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:

The T-Distribution and T-Test “In probability and statistics, Student 's t-distribution (or simply the t-distribution) is a continuous probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small” (Narasimhan , 1996). Similar to the normal distribution, the t-distribution is symmetric and bell-shaped, but has heavier tails, meaning that it is more likely to produce values far from its mean. This makes the t-distribution

Chapter 16 Completely Randomized Factorial ANOVA This tutorial describes the procedures for computing F tests for a completely randomized factorial analysis of variance design. The reading-speed data in Table 16.4-2 of the textbook are used to illustrate the procedures. 1. Enter a description of the data in the SPSS Data Editor following steps 1–4 described in the Frequency Distribution tutorial for Chapter 2. Use rows 1, 2, and 3 of the SPSS Data Editor Variable View window to describe

larger than the mean crime rate at Private Institutions. 3. A confidence interval was requested, at a 95% level for the difference in total campus crime rates between public and private institutions in Minnesota. Utilizing the information in Table 2, summarized from the Sample Data for all colleges in Minnesota, a Confidence interval for the crime rates for Public, and for Private institutions was calculated below. a. Confidence Interval – Public Institutions Input Variables -- Public Institutions

Ethical Behavior at Rocky University Ethical behavior should be expected from college students; however, it is not always present. There is a moral obligation for students, earning a degree, that they are in fact the ones doing the homework and tests. The prevalence of online institutions has helped enable a multitude of working individuals earn a degree. Without the classroom setting, it is arduous for a professor to ensure who is on the other end of the keyboard and monitor. In fact, Gopala, Paswan

Web Calculator Exercise 2 Daniel Alvarado Liberty University Z test & One sample t-test 1. A researcher is interested in whether students who attend private high schools have higher average SAT Scores than students in the general population. A random sample of 90 students at a private high school is tested and and a mean SAT score of 1030 is obtained. The average score for public high school student is 1000 (σ= 200). a. Is this a one- or two tailed test? This test
