... 4) The Wall Street Journal stated that the cost to repair a vacuum cleaner was $54, nationally. In a random sample of 25 vacuum repair jobs in Plano, the mean repair cost was $56.29 with a standard deviation of $6.41. Assume repair costs are normally distributed. Does this indicate the he cost of va ...

Standard deviation (SD) and standard error (SE) are quietly but
... of four. For readers who know that the SD is preferred over the SEM as an index for describing dispersion of gaussian data, the formula for the SEM can be used (in reverse, so to speak) to calculate the SD, if sample size is known. The theoretical meaning of the SEM is quite engaging, as an example ...

... What is a random phenomenon, when do we need to consider it and 6. For continuous variables, what is the probability of a precise value occurring? how can we investigate it using probability and simulation? 7. How do we determine if a given probability distribution is valid? 2. How is the likelihood ...
