A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is
1.34.
A dietician is asked to test this claim and finds that a random sample of
16
servings has a variance of
1.22.
At
α=0.05,
is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below.
A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is
1.141.14.
A dietician is asked to test this claim and finds that a random sample of
2424
servings has a variance of
0.950.95.
At
alpha equals 0.10α=0.10,
is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed.
In a study examining the effect of alcohol on reaction time, Liguori and Robinson (2001) found that even moderate alcohol consumption significantly slowed response time to an emergency situation in a driving simulation. In a similar study, researchers measured reaction time 30 minutes after participants consumed one 6-ounce glass of wine. Again, they used a standardized driving simulation task for which the regular population averages μ = 400 msec. The distribution of reaction times is approximately normal with σ = 40. Assume that the researcher obtained a sample mean of M = 422 for the n = 25 participants in the study. a. Are the data sufficient to conclude that the alcohol has a significant effect on reaction time? Use a two-tailed test with α = .01.
