Question

An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The
manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a
standard deviation of 3 ppm. Suppose that you draw a random sample of 11 printers.

Part iii) Consider the statement: 'The distribution of the mean printing speed of the sampled printers is Normal.'
O A. It is a correct statement, and it is a result of the Central Limit Theorem.
O B. It is an incorrect statement. The distribution of the mean printing speed of the sample is not Normal.
O C.t is a correct statement, but it is not a result of the Central Limit Theorem.

When using the central limit theorem for means with n = 98, it is not necessary to assume the distribution of the population data is normally distributed. True False
3. The range is completely determined by the two extreme scores in a distribution. The standard deviation, on the other hand, uses every score. a) compute the range (choose either definition) and the standard deviation for the following sample of n 5 scores. (note that there are three scores clustered around the mean in the center of the distribution, and two extreme values. SCORES = 0, 6, 7, 8, 14 b) now we break up the cluster in the center of the distribution by moving two of the central scores out to the extremes. Compute the range and the standard deviation. SCORES = 0, 0, 7, 14, 14 c) according to the range, how do the two distributions compare in variability? How do they compare according to the standard deviation?
1. The Central Limit Theorem says that Group of answer choices the distribution of a sum or proportion of randomly selected observations is always normal the distribution of a sum or proportion of randomly selected observations is only normal if the randomly selected observations are from a normal distribution the distribution of a sum or proportion of randomly selected observations eventually gets close to a normal distribution as long as we have a large sample size 2. (Repeated from previous question) A new census bureau reporting method for quantifying the number of "poor" Americans reports 49.1 million people as poor (article linked if you care to read).

In the long run (if they were to take many, many samples of size 1,000), we can expect the the distribution of sample proportions (proportion of each sample who are…
The central limit theorem states that the sampling distribution of sample means has a mean equal to the population -- mean mean mean divided by the population standard deviation mean divided by the population standard deviation standard deviation standard deviation standard deviation divided by the square root of N.

Is it possible for the 50th percentile of a distribution to be equal to the 60th percentile? Why or why not? A. No, because you won’t get the same result multiplying by 50 as you do by 60. B. No, because there will always be some values of the distribution in between the 50th and 60th percentiles. C. Yes, this can happen if the distribution is uniform. D. Yes, this can happen if there are many members of the population with the same value.
5. Suppose X is the number of successes in a random sample of size n from a large population with a proportion of success p.

What does the Central Limit Theorem tell about the sample mean? If the sample size is large, the distribution of all individual observations should be normally distributed. If your sample size is large, the distribution of the sample mean should be normally distributed with the population mean as its center. The distribution of the sample mean is always perfectly normally distributed. O If your sample size is large, the distribution of the population mean should be normally distributed with the population mean as its center.
