THE STANDARD DEVIATION OF THE IQ SCORES OF 25
IQ scores: Scores on an IQ test are normally distributed. A sample of 25 IQ scores had standard deviation s = 8. The developer of the test claims that the population standard deviation is less than o = 10. Do these data provide sufficient evidence to...

13.2.1 GO Tutorial X Note that we reject the null hypothesis of equal treatment means when the test statistic is large enough. An article in Environment International (Vol. 18, No. 4, 1992) describes an experiment in which the amount of radon released in showers was investigated. Radon-enriched water was used in the experiment, and six different orifice diameters were tested in shower heads. The data from the experiment are shown in the following table. Orifice Diameter Radon Released (%) 0.37...

Hypothesis Tests for Means
11. In one year, an online travel agency reported that summer travelers booked their airline reservations an average of 71.1 days in advance. A random sample of 40 summer travelers in a later year was selected, and the number of days travelers booked their airline reservations in advance was recorded. The data are shown in the accompanying table. Complete parts a and b below. Click the icon to view the data table. a. Perform a hypothesis...
