A study was carried out to determine the influence of a trace elementfound in soil on the yield of potato plants grown in that soil, defined asthe weight of potatoes produced at the end of the season. A large fieldwas divided up into 14 smaller sections for this experiment. For eachsection, the experimenter recorded the amount of the trace elementfound (in milligrams per metre squared) and the corresponding weightof the potatoes produced (in kilograms). This information is presentedin the worksheet ‘Dataset5’ in the Excel document. Define X as thetrace element amount and Y as the yield.1. Draw a scatterplot of your data set.Page 52. Calculate the coefficients of a linear equation to predict the yieldY as a function of X.3. Calculate the correlation coefficient for the paired data values.4. Set up the framework for an appropriate statistical test to establish if there is a correlation between the amount of the trace element and the yield. Explain how having the scatterplot referredto…

TEACHER Weatherwse is a magazine pubilished by the American Meteorological Soclety. One issue grves a rating system used to classity Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 40 waves showed an average wave height of x 16.7 feet. Previous studies of severe storms indicate that 35 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use 0.01. (a) What is the level of significance? State the nul and alternate hypotheses Hel 16.4 Ht >16.4 t Mo 16.4 t, H< 164R Ho: - 16.4 t, H 16.4 R Hot 16.4 n; H- 16.4 t H < 16.4 n; H- 164n (b) What sampling distribution will you use?
