In a study of reaction time (in seconds) to a medicine given to 5 cancer patients, an Oncologist recorded the data 10, 20, 30, 25, 15. Find the standard deviation. => 7.1 or 50 or 20 or 15.81..

Based on a study, the mean family income in the US was $38,000 with a standard deviation of 21,000. If a consulting agency surveys 49 families at random, what is the probability that it finds a mean family income of more than $41,500? => 1.21% or 12.1% or 98.79% or 87...

The concept of limits leads to define and describe continuity and derivative of the function. The continuity of a function has practical as well as theoretical importance. We plot graphs by taking the values generated in the laboratory or collected in the field. We connect the p..

A researcher wishes to estimate the average daily wage (industrial composite) of industrial workers. A previous study showed that the standard deviation is $23. How large a sample must be selected if he wants to be 99% confident of getting an interval that contains the..

A survey reports that the average coffee consumption of the American adult is over 400 cups per annum. The annual coffee consumption of 25 American adults was subjected to a study and it was found that the sample has a mean of 418 cups and a standard deviation of 10 cu..
