Determine wheaten the graph can represent a normal curve, if it cannot explain why ?
are you able to help me produce a graph which includes all of this Use the data generated in the laboratory to prepare a table and graph of the results, with a written summary. To include: Table of summary results that is mean and SD (standard deviation) only (not individual numbers for each tube) Graph of change in whatever parameter (plot the mean and error bar using the standard deviation) is used to determine the effect on the vegetable on the y-axis against sugar/NaCl concentration on x-axis, put both parameters on one graph. Do a correlation graph so add a correlation, R2 number, find this in Excel – add trendline and under trendline look for more options and at bottom at R2 to graph. Then in discussion use this value to comment on whether or not a correlation between the changes and the findings. Text: short summary of the key findings - NOT what happens for each tube but the general trend of the results and the correlation coefficient. with these set of results Solution…
Age of College Students Find the 90% confidence intervals for the variance and standard deviation of the ages of seniors at Oak Park College if a random sample of 20 students has a standard deviation of 2.2 years. Assume the variable is normally distributed. Use the chi-square distribution table to find any chi- square values to three decimal places. Round the final answers to one decimal place.
