value of alpha is associated to the confidence level of the statistic problem. If alpha is not given use .05% Confidence levels refer to the percentage of all possible samples that can be expected to include the true population parameter. If the confidence level is not given use 95% The mean is the average of all numbers. To calculate mean, add together all of the numbers in a set and then divide the sum by the total count of numbers. Confidence intervals estimate population parameters, such

MAT 300 – Assignments and Rubrics ALEKS Pie Completion Worth 400 points The primary goal of this class is for you to complete the entire pie by the end of the term. Points for pie completion will be added to your score at the end of the term. ALEKS Emphasis on Lab Work. On-ground sections of the course will be taught in a computer lab, with three (3) hours of lab time using ALEKS for every one (1) hour of traditional instruction. Thus, students in an onground section of the course will log

In a Word document, write a two to three (2-3) page report in which you: Calculate the mean, median, and standard deviation for ounces in the bottles. Round your final results to 3 significant places after the decimal. Construct a 95% Confidence Interval for the ounces in the bottles. Round your final results to 3 significant places after the decimal. Conduct a hypothesis test to verify if the claim that a bottle contains less than sixteen (16) ounces is supported. Use 0.02 as the level of

M&M Project Math 336 (1) Buy a packet of regular size M&M's. Record the frequency of each color and then transfer this information to a bar chart and a pie chart. (2) Represent the number of M&M's per packet on a histogram using all of the class data. Is your histogram normally distributed? Check using the empirical rule. Also choose your favorite color and draw a histogram of the number of M&M’s of that color per packet based on class data. Draw a box-plot of the total number of data in
