Question

Suppose an All Greens store in Sonoma, California, wants to estimate a range of advertising costs appropriate to its store. If it spends too little on advertising, it will not reach enough customers. However, it does not want to overspend on advertising for this type and size of store. At this store, x₁ = 163, x₂ = 2.4, x₃ = 188, x₅ = 6.6, and x₆ = 10. Use these data to predict x₄ (advertising costs) and find an 80% confidence interval for your prediction. (Use 2 decimal places.)
