When dragons on the fictional planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 32% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 48 of the dragon eggs to incubate. Consider all the possible samples of 48 dragon eggs. Round answers to 4 decimal places. a) Compute the mean number of yellow eggs in samples of 48 eggs? (that is the same as asking for the expected value of the number of yellow eggs)mean = b) Compute the standard deviation in the number of yellow eggs in samples of size 48?standard deviation = c) Compute the variance in the number of yellow eggs in samples of size 48?variance =

. There are 20290 protein coding genes in the human genome. The total length of all 22 autosomal chromosomes plus the two sex chromosomes is 1052 mm. The length of the X chromosome is 53 mm. We assume that the size of protein coding genes is equal among chromosomes. We're interested in testing whether the number of protein coding genes is evenly distributed among chromosomes including the sex chromosomes. Calculate the EXPECTED number of protein coding genes on the X chromosome.
A farmer sows 100 seeds of a new type of corn and wants to quickly determine the yield, or total number of ears of corn, for the crop when it has matured. He decides to take a simple random sample of 10 corn plants. He labels the 100 plants 00-99. Refer to the given line from a random number table. Which numbers represent the sample of 10 corm plants? 58160 0969538399 40400 32662 46254 O 58, 16, 00, 96, 95, 38, 39, 94, 04, 00 O 58, 16, 00, 96, 95, 38, 39, 94, 04, 32 O 58, 16, 96, 95, 38, 39, 94, 04, 32, 66 58, 16, 09, 69, 38, 39, 40, 32, 66, 46

What is the sample proportion, p, of defective tablets? c. How can the discrepancy between the population proportion and the sample proportion be explained? a. The population proportion of defective aspirin tablets is p = (Round to three decimal places as needed.) b.

A study of n = 2252 adults age 18 or older found that 72% of the cell phone users send and receive text messages.15 A study of n = 800 teens age 12 to 17 found that 87% of the teen cell phone users send and receive text messages. What is the best estimate for the difference in the proportion of cell phone users who use text messages, between adults (defined as 18 and over) and teens? Give notation (as a difference with a minus sign) for the quantity we are trying to estimate, notation for the quantity that gives the best estimate, and the value of the best estimate. Be sure to clearly define any parameters in the context of this situation.
