A random variable X is said to follow a lognormal distribution if Y = log(X) follows a normal distribution. The lognormal is sometimes used as a model for heavy-tailed skewed distributions.
please answer the follow:
A) Please refer following image for Histograms.
Log transformed data have a more normal looking histrogram.
B) Please refer following image for Normal probability plot.
Log transformed data have a better normal probability plot.
C) Correlation test based on normal probability plot - based on the normal probability plots one caan conclude that LOG(Y) follows a lognormal distribution and correlation between Y and LOG(Y) is quite high.
In this case it is 0.90

For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...
For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...
A soft drink manufacturer uses fire agents to handle premium distribution for is various products. The marketing director desired to study the timeliness with which the premiums are distributed. Twenty transactions for each agent were selected at random and the time lapse (in days) for handling each transaction was determined. The results follow: Agent 1 Agent 2 Agent 3 Agent 4 Agent 5 24 18 10 15 33 24 20 11 13 22 29 20 8 18 28 20 24...
) Is the relationship between weight and height a linear one? The “Pr_3.csv” file contains data that includes weight (in pounds) and height of children (in inches)ages 3 months to twelve years.A. Create a scatterplot of weight vs. height squared. Does it appear that a linear relationship exists between weight and height squared?B. Perform a simple linear regression analysis using height squared to predict weight. What is the regression equation you found?C. Perform a model utility test. Does height squared...

Please show how you did this in excel. :13-19 Every home football game for the past eight years at Eastern State University has been sold out. The revenues from ticket sales are significant, but the sale of food, beverages, and souvenirs has contrib- uted greatly to the overall profitability of the football program. One particular souvenir is the football pro- gram for each game. The number of programs sold at each game is described by the following probabil- ity distribution:...
In this problem, we have 100 items. Each item is characterized by a tuple (A, B), where A is the cost of the item and B is the weight of the item.Then, We would like to find a set of items such that their total cost is maximized while their total weight does not exceed 2000i need helping finding the maximum profit and the index number of items to acheive the profit (the index number starts from #1)84, 39)(78, 79)(91,...
