Weights of golden retriever dogs are normally distributed. Samples of weights of golden retriever dogs, each of size nequals15, are randomly collected and the sample means are found. Is it correct to conclude that the sample means cannot be treated as being from a normal distribution because the sample size is too small? Explain. Choose the correct answer below. A. Yes; the sample size must be over 30 for the sample means to be normally distributed. B. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size. C. No; the samples are collected randomly, so the sample means will be normally distributed for any sample size. D. No; as long as more than 30 samples are collected, the sample means will be normally distributed.

The following observations are on stopping distance (ft) of a particular truck at 20 mph under specified experimental conditions (“Experimental Measurement of the Stopping Performance of a Tractor-Semitrailer from Multiple Speeds,” NHTSA, DOT HS 811 488, June 2011): 32.1 30.6 31.4 30.4 31.0 31.9 The cited report states that under these conditions, the maximum allowable stopping distance is 30. A normal probability plot validates the assumption that stopping distance is normally distributed. a. Does the data suggest that true average stopping distance exceeds this maximum value? Test the appropriate hypotheses using a 5 .01.

According to the Shannon Diversity Index, which of the five blocks above, with each containing 36 squares, would show the greatest diversity? The different shades represent different species, and more squares of a shade represent higher abundance. Use the figures to answer the following question. Five blocks are shown. Block 1 has 18 white squares and 18 light gray squares. Block 2 has 9 white squares, 18 light gray squares, and 9 dark gray squares. Block 3 has 23 light gray squares and 13 dark gray squares. Block 4 has 6 white squares, 2 light gray squares, 4 dark gray squares, and 24 black squares. Block 5 has 9 white squares, 9 light gray squares, 9 dark gray squares, and 9 black squares. According to the Shannon Diversity Index, which of the five blocks above, with each containing 36 squares, would show the greatest diversity? The different shades represent different species, and more squares of a shade represent higher abundance. 5 2 1 4
