Question

A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is

1.23.

A dietician is asked to test this claim and finds that a random sample of

servings has a variance of

1.27.

α=0.10,

is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed.

(b) Find the critical value(s).

I do not know how to calculate the critical value with my calculator. I have a TI83+.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
