And. For a continuous frequency distribution we must assume that all the data occurrs at the mid point of classes.
First of all we find mid point for each class
Mid point x = ( lower limit + upper limit)/2
Then multiply mid point x with the corresponding frequency and then add up and finally summing value is divided by total frequency.
The correct answer is (c).

Homework 4 Use the hand span data that we collected in class for homework Suppose you want to buy someone a pair of love, but you do not know their love size. Usually, we do have a pretty good idea of the person's height. Let' asume that the right hand span is a rood indicator of the love size. So let find the best predictor of right hand span be on the person's height. Once we can predict the right...

True or False (1 point each) (Correct the ones that are false) The purpose of an interval estimate is to provide information about how close a point estimate, i.e. sample statistic, is to the population parameter. If the population standard deviation is unknown and cannot be estimated from historical data, an interval estimate for the population mean can be constructed by substituting the sample standard deviation and using the t distribution instead of the normal distribution. You cannot determine a...
