1. Frequency and Relative Frequency Distribution. What is the shape of the distribution of your sample data? Which class best estimates the center of the distribution? Do you have any modes? Are there any outliers? Make a guess as to the shape of the population distribution from the above histogram.Use 2 decimal places for all values. Confidence interval Construction Validate the Assumptions/Conditions to construct a 95% Confidence interval. What is the symbol and value of the critical value for this interval? (You must interpolate.) Write the formula...
The frequency distribution in the following table lists the results of a quiz given in Professor Gilbert's statistics class. Find the mean, median, and mode of the scores. (Round answer for mean to one decimal place. Enter solutions for mode from smallest to largest. If there are any unused answer boxes, enter NONE in the last boxes.)
