MATH 225N Week 5 Understanding Normal Distribution; complete solutions guide "A" 2024• Lexie averages 149 points per bowling game with a standard deviation of 14 points. Suppose Lexie's points per bowling game are normally distributed. Let X= the number ofpoints per bowling game. Then X∼N(149,14). Suppose Lexie scores 186 points in the game on Tuesday. The z-score when x = 186 is - no response given. The mean is - no response given. This z-score tells you that x = 186 is -...

MATH 225N Week 4 Discussion: Probability Consider when you are listening to a new patient who says they have had a fever for 3 days. You would use your knowledge and experience with probability to come to a diagnosis. What changes those probabilities? Is it age, is it other symptoms, is it new study results? What is the source of these probabilities and what causes these probabilities to change? This discussion is not to debate diagnoses, but to focus on the sources and influences on proba...

MATH 225N Week 5 Assignment: Applications of the Normal Distribution – Excel Question Sugar canes have lengths, X , that are normally distributed with mean 365.45 centimeters and standard deviation 4.9 centimeters. What is the probability of the length of a randomly selected cane being between 360 and 370 centimeters? • Round your answer to four decimal places. The mean is μ=365.45 , and the standard deviation is σ=4.9 . As the probability between two values is to be calculated, su...

Central Limit Theorem for Proportions Week 5 Assignment: 1. A dental student is conducting a study on the number of people who visit their dentist regularly. Of the 520 people surveyed, 312 indicated that they had visited their dentist within the past year. Find the population proportion, as well as the mean and standard deviation of the sampling distribution for samples of size n=60. Correct answers: The population proportion is p=≈0.600. This is also the mean of the sampling distrib...
