Each column represents a different game, with betting and actual scores noted.*| **Betting** | 2 | 1 | 6 | 3 | 5 | 7 | 4 | 6 | 2 | 4 | 1 | 5 | 1 | 5 | 2 ||-------------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|| **Actual** | 18 | 9 | 1 | 8 | 6 | 6 | 9 | -3 | 4 | -1 | 11 | 5 | 7 | 11 | 3 | -7 |**Task: Constructing a Confidence Interval**Construct a 95% confidence interval for the mean value of the actual spread when the betting spread is 1. Round your answers to two decimal places.**Graph/Diagram Explanation:**The table above displays the spreads, with each column indicating a particular game. The betting row denotes the predicted spread, while the actual row shows the outcome spread. The data assists in examining the accuracy of betting predictions across these games.

The college physical education department offered an advanced first aid course last summer. The scores on the comprehensive final exam were normally distributed, and the z-scores for some of the students are shown below. Robert 1.24 Juan 1.66 Haley −1.84 Joel 0.00 Jan −0.84 Linda 1.68 Which of these students scored above the mean? (Select all that apply.) Which of these students scored on the mean? (Select all that apply.) Which of these students scored below the mean? (Select all that apply.) If the mean score was μ = 140 with standard deviation σ = 15, what was the final exam score for each student?
O Macmillan Learning The domestic cat, Felis catus, is a domesticated furry creature often kept as a pet in many countries. Suppose a volunteer at a local animal shelter wanted to find out a little more about the cats in her care. The volunteer carefully measured the height for the 10 fully grown adult cats at her shelter. The height measurements were taken from the base of the foreleg to the shoulder. The table shows the results of the measurements. Calculate the mean, variance, and standard deviations for cat height for the sample of shelter cats. Report all your answers to two decimal points. mean: variance: standard deviation: in in² in Sample 1 2 3 4 5 6 7 8 9 10 Height (in) 10.5 13 7.7 7.5 9.55 10.5 10.85 12.3 8.15 7.85
