The sugar content per 50 gram serving size was computed by using the following formula: 50 grams = Serving size to be compared (50 x Sugar per serving) / Serving Size Example: (50 * 1) / 30 = 1.67g of sugar per 50.00g serving A histogram was created using a bar chart to display the sugar content per 50 gram serving size of the various cereals. The raw data (sugar content and serving size) was obtained from

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

Introduction Statistics is a field of knowledge that enables an investigator to derive and evaluate conclusions about a population from sample data. In other words‚ statistics allow us to make generalizations about a large group based on what we find in a smaller group. The field of statistics deals with gathering‚ selecting‚ classifying data; interpreting‚ analysing data‚ deriving‚ evaluating the validity and reliability of conclusions based on data. Strictly speaking‚ the term "parameter" describes
