Question Help A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.15. A dietician is asked to test this claim and finds that a random sample of 16 servings has a variance of 1.06. At a = 0.05, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below. (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is(are) (Round to two decimal places as needed. Use a comma to separate answers as needed.) Choose the correct statement below and fill in the corresponding answer boxes. O A. The rejection region is x2< O B. The rejection region is x2 > OC. The rejection regions are x2 < and y2 > (c) Find the standardized test statistic y2. (Round to two decimal places as needed.) ?

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
