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

Association and Causation Statistics is the science pertaining to the collection and analysis of data. It is the refinement of the ambiguous‚ the distilling of truth from the crudest of resources. For this reason‚ it is necessary to discern the simplest path from Point A to Point B‚ disregarding any unnecessary data that may lie in the path. This‚ however‚ is easier in theory than in practice‚ and statisticians have developed various techniques to help differentiate between causation‚ a variable

Does asymptotic mean that the normal curve gets closer and closer to the X-axis but never actually touches it? Yes‚ asymptotic means that the curve of a line will approach 0 (the x-axis)‚ but it will not touch 0 and instead will extend to infinity. In this class‚ this applies to the normal continuous distribution and is one of the 4 key characteristics of a normal continuous distribution that our text book discusses. This means that the curve of the line will extend infinitely in both the negative
