1. Are the assumptions and conditions for inference satisfied?
A. The Randomization Condition is met. The Normal probability plot is relatively straight, but the histogram is bimodal and asymmetric, so the Nearly Normal Condition is not met.
2) Find a 95% confidence interval for the true mean number of calories per serving. _____<μ(calories)<____ (Round to two decimal places as needed.)
3) A diet guide claims that you will get an average of 130 calories from a serving of vanilla yogurt. What does this confidence interval indicate about this claim?
A.The confidence interval is entirely above the diet guide's claim of 130 calories, so this claim is supported by the confidence interval.
