Human measurements provide a rich area of application for statistical methods. The article "A Longitudinal Study of the Development of Elementary School Children's Private Speech" (Merrill-Palmer Q., 1990: 443-463) reported on a study of children talking to themselves (private speech). It was thought that private speech would be related to IQ, because IQ is supposed to measure mental maturity, and it was known that private speech decreases as students progress through the primary grades....

Human measurements provide a rich area of application for statistical methods. In a longitudinal study the development of elementary school children explored the relationship between 1Q and private speech. Private speech is considered to be when children talk to themselves. It was thought that private speech would be related to 1Q, because 1Q is supposed to measure mental maturity, and it was known that private speech decreases as,students progress through the primary grades. The study included 34 students...

24) Two groups of randomly selected drivers are surveyed to see how many miles per week they drive for pleasure trips. At alpha equal to 0.01, can it be concluded that single drivers do more driving for pleasure trips on average than married drivers? Assume the population standard deviation for single drivers to be 16.7 and the population standard deviation for married drivers to be 16.1. Test the hypothesis using the methods listed below. Single drivers 110 97 Married drivers...
