Identify the sample by naming the sampling technique used.Divide the users of the computer online service Internet into different age groups and then select a random sample from each age group to survey about the amount of time they are connected to the internet each month.

Refer to problem 34. The frequencies, in order, are:

A random sample of 30 computer outlet stores were selected in the New York area and the price of a More Joy joystick was checked at each store. The results to the nearest dollar follow:78, 65, 92, 100, 99, 63, 82, 87, 91, 95, 102, 73, 69, 75, 86, 94, 97, 112, 115, 76, 89, 96, 94, 69, 70, 72, 80, 100, 90, 74Make a frequency table using five classes. The classes are:

Classify the following as being observational or experimentalA survey of Americans was conducted to determine how many soft drinks they consumed each day.

In Thoroughbred horses, Equine Familial Isolated Hypoparathyroidism (EFIH) is an autosomal recessive disorder that causes severe hypocalcemia in foals. In a population of 11,500 Thoroughbreds, 6 are affected with EFIH. Assume the population is in Hardy–Weinberg equilibrium. What is the estimated frequency of the recessive allele in the population?

Based on the information in the previous question, if a Callipyge ram is bred to a Callipyge ewe, what is the probability of producing Callipyge offspring? 

Which of the following is an example of incomplete penetrance? 

Based on the narrow-sense heritability values calculated in the previous two questions, which trait—ribeye area in Limousin cattle or average milk yield in Simmental cattle—is expected to respond more rapidly to selection? 

In a herd of Limousin cattle, the average ribeye area is 85 cm². The breeder selects bulls and heifers averaging 95 cm² to produce the next generation. The average ribeye area of their calves is 87.5 cm². What is the narrow-sense heritability?
