strong evidence that the gambler’s claim is true? a. Specify the null and alternative hypothesis for this problem. p = probability gambler guess correctly for an individual roll null (Ho): p = 1/6 alternative (Ha): p > 1/6 b. Find the test statistic and calculate the p-value. What do you conclude? pˆ = 0.2 so z = (0.2-0.1667)/ .1667(.8333) /100 = 0.894. From the table the p-value is between 18% and 19%. The null hypothesis is a reasonable explanation of this data so we do not have strong evidence

Prison is just a place where criminals get a good spanking and endless lectures on behavior until they can learn how to be righteous.

Section 1.1 - Introduction to the Practice of Statistics 1. Explain the difference between a population and a sample. A population is the entire group to be studied and a sample is a portion of the population. 2. Explain the difference between a parameter and a statistic. A statistic is a numerical summary of a sample and a parameter is a numerical summary of a population. 3. What is Descriptive Statistics and how is it used? Descriptive statistics describes the results of a sample without

CHAPTER 1 Individuals are the objects described by a set of data. Individuals may be people‚ but they may also be animals or things. A variable is any change of an individual. A variable can take different values for different individuals. A categorical variable places an individual into one of several groups or categories. A quantitative variable takes numerical values for which arithmetic operations such as adding and averaging make sense. The distribution of a variable tells us what values

The representative sample is a subset of a population of interest that is exhibiting the typical characteristics of the population.
