Also what is the standard of error

Summary statistics for yield (in bushels per acre) of soybean crops when treated with a particular pesticide are shown below. Statistic Value Sample Size 20 Mean 46.2 Standard Deviation 6.5 Find a 95% confidence interval for the mean yield. Give all of the requested values as numbers only (no notation or labels) You may refer to the Critical Values for a Cl handout as needed. In the next question, type your answers to all of the following. Clearly label answers with quesion parts. Theoretic distributions: . Normal . t with df . Chi-square with df . F with of for groups and df for error A. Choose a distribution from the list above and indicate clearly which distribution and how many degrees of freedom, if applicable. B. Check conditions for using this distribution. Explain specifically what you checked and indicate whether conditions are met. Indicate whether more information would be needed to check conditions and, if so, what you would need to know. C. Give the confidence interval. D. Interpret the confidence interval
