I need excel step by step how to create the charts and report skewness, please.

#1. Researchers wanted to test whether people's mood (bad vs. good) affected their generosity (measured in donated dollars). Formulate and report: 1) a null hypothesis, 2) a non-directional research hypothesis, 3) a directional research hypothesis.

#2. (10 points)Use the datasetHW_Dataset1.For the variable MONEY, include a histogram made with "Charts"; make sure it has 6 bins and the y-axis is labeled as "Frequency".

Find and report skewness and kurtosis for the MONEY variable. Include a few words to comment on the obtained skewness and kurtosis: 1) Is the distribution of MONEY scores symmetrical, positively skewed, or negatively skewed? 2) Is the distribution of MONEY scores platykurtic, mesokurtic, or leptokurtic?

#3. (10 points)Researchers explored different ways to mitigate anxiety in college students. Participating in this research study students were randomly assigned to one of the three experimental conditions: placebo, exercise, or drug. After two weeks of the corresponding treatment, students were tested on anxiety using a standardized questionnaire (0-100 scale). Report independent and dependent variables. Specify whether each variable is categorical or continuous. Formulate and report a null hypothesis.
