Question
A company tested 11 random brands of vanilla yogurt and found the number of calories per serving given below. Complete parts 1 through 3 below.
133    162     155     123     113     109     174     165     112     127     98   
 
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.
 
B. The Randomization Condition is met. The Normal probability plot is relatively straight and the histogram is roughly unimodal and​ symmetric, so the Nearly Normal Condition is met.
 
C. The Randomization Condition is not met. The Normal probability plot is relatively straight and the histogram is roughly unimodal and​ symmetric, so the Nearly Normal Condition is met.
 
D. The Randomization Condition is met. The Normal probability plot is not roughly straight and has an​ outlier, and the histogram is skewed​ right, 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.
 
B. The confidence interval contains the diet​ guide's claim of 130 ​calories, so this claim is supported by the confidence interval.
 
C. The confidence interval is entirely above the diet​ guide's claim of 130 ​calories, so this claim is not supported by the confidence interval.
 
D. The confidence interval is entirely below the diet​ guide's claim of 130 ​calories, so this claim is not supported by the confidence interval.
