... 4. State police believe that 70% of the drivers traveling on I-10 exceed the speed limit. They plan to set up a radar trap and check the speeds of 80 cars. a) What is the expected proportion of speeding cars? b) What is the standard deviation of the proportion of speeding cars? c) Verify if the appr ...

... If F is significantly larger than 1, it means that the empirical estimate of variability between group means is significantly larger than the theoretical estimate under the null hypothesis that all populations have the same mean, and we reject H0. The degrees of freedom for the F test are c–1 and N ...

... It describes the variability of sample means that could occur just by chance and thereby serves as a frame of reference for generalizing from a single sample mean to a population mean. It allows us to determine whether, given the variability among all possible sample means, the one observed sample m ...
