Winter The output shows an attempt to model the association between average January Temperature (in degrees Fahrenheit) and Latitude (in degrees north of the equator) for 59 U.S. cities. Which of the assumptions for inference do you think are violated? Explain.
Week 8: Normal Distribution 25 October 2016 Basic Statistics for Research Professor HK Dong Wendy Liu Probability density function f(x) – describes the distribution of probability for the continuous random variable. It has the properties The total area under the probability density curve is 1 area under the probability density curve between a and b for all x Normal distribution – bell-shaped density curve Mean = µ Standard deviation = σ Normal distribution w/ mean of µ and st. dev of σ is denoted by N(µ, σ) Standard normal distribution: N(0,1) Groundwork for Inferential Statistics Sampling distribution of a statistic o distribution of all possible observations of the statistic for samples of
