Park Rangers in a Yellowstone National Park have determined that fawns less than 6 months old have a body weight that is approximately normally distributed with a mean µ = 26.1 kg and standard deviation σ = 4.2 kg. Let x be the weight of a fawn in kilograms. Complete each of the following steps for the word problems below: Rewrite each of the following word problems into a probability expression, such as P(x>30). Convert each of the probability expressions involving x into probability expressions involving z, using the information from the scenario. Sketch a normal curve […]
In this problem, we will find numerical and graphical summaries of the Titanic dataset using R.
1. In this problem, we will find numerical and graphical summaries of the Titanic dataset using R. The dataset consists of information on all the passengers of the ill – fated trans – Atlantic ship Titanic. We are looking at only 3 columns (variables) in the dataset, namely Age, Sex and Survival status of the passengers. The dataset “titanic_as.RData” is (.RData is a convenient R data format) available in the homework folder on Carmen. Load the file using the command: load(“titanic_as.RData”) Note, if you are not in the same directly as the .RData file then you need to put the […]
A tube of Listerine Tartar control toothpast contains 4.2 ounces. As people use the toothpaste, the amount remaining in any tube is random.
A tube of Listerine Tartar control toothpast contains 4.2 ounces. As people use the toothpaste, the amount remaining in any tube is random. Assume the amount left in the ube follows a uniform distribution. a. how much toothpaste would you expect to be remaining in the tubeb. what is the std deviation of the amount remaining??c. what is the likelihood there is less than 3.0 oz remaining?d. what is the probability there is more than 1.5 oz remaining?
