STA 2023 Lecture Notes - Lecture 27: Standard Deviation, Skewness, Quartile
Document Summary
The standard normal distribution curve can be used to solve a wide variety of practical problems. The only requirement is that the variable be normally or approximately normally distributed. For all the problems presented in this chapter, you can assume that the variable is normally or approximately normally distributed. To solve problems by using the standard normal distribution, transform the original variable is transformed, then the procedure table and table e in appendix c can be used to solve problems. The average annual salary for ally u. s. teachers is ,750. Assumme that the distribution is normal and the standard deviation is . Find the probability that a random selected teacher earns: between k and k a year. 91. 38: if you were applying for a teaching position and were offered k a year, how would you feel (based on this information) The mean number of miles driven per vehicles annually in the united states is.
