Question 2 Which of the following tools is used to assess the normality of a distribution? histogram O pie chart O scatterplot normal quantile plot

Post your created histogram. How would you describe the distribution? (Symmetric, skew left, skew right? Is it unimodal or bimodal?) Picture is below .

Hi, I want to doubl check my answer for this histogram. On question #2 Type of distribution I choosed Chi Square Distribution by looking at the data (not sure if mi correct). And I need mostly help with #3. Could you explain how to find mean and median "given 30 pulse rate" using excel?

Question: How to describe normal distribution and skewed in the histogram and density plots in general. Also, explain any correlation we observe between the response and predictor variables in any scatter plots in general.

Use the given data values​ (a sample of female arm circumferences in​ centimeters) to identify the corresponding z scores that are used for a normal quantile​ plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile​ plot, then determine whether the data appear to be from a population with a normal distribution. 33.9​, 37.9​, 43.8​, 32.8​, 40.1 Question content area bottom Part 1 List the z scores for the normal quantile plot.   Part A -List the z scores for the normal quantile plot.     Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form​ (x,y), where x is the sorted arm circumferences in ascending​ order, and y is the corresponding z score.   Part C- Do the data come from a normally distributed​ population?
