Statistics: Please provide steps and some explanation Construct a stem and leaf diagram, a frequency distribution table, plus develop a bar chart, pie chart, histogram, polygon and an ogive from the following data set. When you construct the pie charts, bar graphs, etc. Use the calculation of 2K to find the number of classes you will need to construct the frequency distribution table. You will need to use lower class limits, lower-class boundaries, midpoints upper-class boundaries, upper-class limits, frequency, relative...

Given: Assume you have collected data from 150 subjects, and that the distribution of the data is a "normal" distribution. The mean of the scores is 37, with a standard deviation of 4.5. Using the given information, calculate the 68% confidence interval. A confidence interval represents a range of values, the lowest value is references as the "lower bound", the highest value is referenced as the "upper bound". Determine the lower and upper bounds for the 68% confidence interval. Round...

Healthy women aged 18 to 40 participated in a study of eating habits. Subjects were given bags of potato chips and bottled water and invited to snack freely. Interviews showed that some women were trying to restrain their diet out of concern about their weight. How much effect did these good intentions have on their eating habits? Here are the data on grams of potato chips consumed (note that the study report gave the standard error of the mean rather...

Two decision rules are given here. Assume that the quality characteristic follows a normal distribution and the control chart has two-sigma control limits, and the sample size is ? = 4. Rule 1: If one or more of the next 3 samples yield values of the sample average that fall outside the control limits, conclude that the process is out of control. Rule 2: If all of the next 5 samples fall on the same side of the center line,...

Here is a series of address references given as word addresses: 18, 19, 27, 16, 21, 0, 64, 48, 19, 11, 19, 22, 4, 27, 6, and 27. Assuming a direct-mapped cache with 16 one-word blocks that is initially empty, label each reference in the list as a hit or a miss and show the final contents of the cache.
