8. It is not possible to arrive at an explicit margin of error in predicting either the variance/standard deviation or the ratio of variances/standard deviations of population(s) from samples. Why is this so?
t 2:19 K The acceptable level for insect filth in a certain food item is 4 insect fragments (larvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 50 ten-gram portions of the food item is obtained and results in a sample mean of x = 4.6 insect fragments per ten-gram portion. Complete parts (a) through (c) below. Click here to view the standard normal distribution table (page 1) Click here to view the standard normal distribution table (page 2). (a) Why is the sampling distribution of x approximately normal? A. The sampling distribution is assumed to be approximately normal. B. The sampling distribution is approximately normal because the population is normally distributed and the sample size is large enough. OC. The sampling distribution is approximately normal because the sample size is large enough. D. The sampling distribution is approximately normal because the popluation is normally distributed. (b) What is the mean and standard deviation of the sampling…
You are hanging out with your friend on a Saturday night and they decide they want to watch the Ultimate Fighting Championship Event happening that night. As you are watching the mixed martial arts fights you notice that males and females fight separately. You talk to your friend about this and find out that it is due to "safety and sizing" that the sexes do not fight each other. You (being a statistics enthusiast) decide to compare skills between the sexes to see if there is a true difference between the fighters' ability. You take the top 10 male fighters and the top 10 female fighters win/loss ratios (yes these I actually looked up): Male Fighters Female Fighters 19 7.3 23 2.8 21 4.2 2.8 10.5 2.4 2.8 3.2 15 4 5.3 3.9 26 3.8 4 5 3.8
