Examine the spreadsheet of the StatCrunch data set Treating Depression Study (Links to an external site.). Out of the first ten individuals in the data set who were assigned to the Lithium treatment group, how many had a recurrence of depression during the study?
Instructions For this assignment, you will use Excel or StatCrunch to compute confidence intervals and test statistics/p-values for a hypothesis test using proportions. You should practice typing math notation using Word.
Question: This question requires you to use StatCrunch to create frequency distributions & bar graphs. Each part of the question that requires StatCrunch includes directions for creating the output in the software. First you need to open the dataset in StatCrunch: • If your instructor has asked you to join a StatCrunch Group, open the dataset Bipolar Depression Study.
2. Use the calculator in StatCrunch to find the probability distribution and include the graphic from StatCrunch in your response. 3. What is the mean and standard deviation of your Binomial distribution? 4. Make up your own less than, greater than, and a between probability problem. For example, P (x<8) or P (5<x<10).

Summary Statistics, Boxplots, and Outliers 8) Using StatCrunch, find the summary statistics for Lowest MSRP data. 9) Using StatCrunch, construct a horizontal boxplot for the Lowest MSRP data.
DetailsObjective: Use StatCrunch to find test statistics and P-values from a set of data to perform a formal hypothesis test.Assignment: Open the handout for directions to obtain the main data set from StatCrunch database. Once you complete have the main set in ascending order, you are to take your sample.
Write the equation of the regression equation below as displayed in page 1 of 2 of the StatCrunch output window (or even better just copy and paste the equation). Round the values to two decimal places. Identify the slope and y-intercept and interpret each in context. Identify r-squared and round to 4 decimal places.
Use StatCrunch to find expected counts, the Chi-square test statistic and the P-value. (directions) Copy and paste your StatCrunch table into your post. How many males in the sample are expected to answer yes to question about alcohol consumption in the last two hours? Show how to calculate this expected count and explain what it means relative to the hypotheses. Explain how we know that this ...
