PPT-Stats for Engineers Lecture 7

Confidence intervals During component manufacture a random sample of 500 are weighed each day and each day a 95 confidence interval is calculated for the mean weight of the components On the first day we obtain a confidence interval for the mean weight of . Recap: Linear regression. Linear regression: fitting . a straight line . to the . mean. value of . as a function of .  . We measure a response variable . at various values of a controlled variable .  .  .  . Summary from last time. Discrete Random Variables. Binomial distribution . . – number . of successes from . independent Bernoulli (YES/NO) trials.  .  . Standard deviation . – measure spread of distribution. Summary From Last Time.

Hypothesis: We believe that some of the Eagles’ stats will be linear and have a positive correlation (meaning that the best-fitting line should be increasing, or the variable . r. should be as close to 1 as possible and go through as many points as possible).. 11.
