In: Statistics and Probability
You have been breeding roaches in your dorm and are trying to increase the speed in your roach population. You measure speed by timing how quickly the roaches race along the linear track in your dorm room. Your current population mean is 6.2 seconds with a standard deviation of 0.41 sec. You selected the fastest 5% of your current population to be parents of the next generation. The broad and narrow sense heritability values for racing speed in roaches are 0.92 and 0.81, respectively. You wish to develop a faster population of roaches. Round all answers properly to three decimal digits. Enter all answers without units so that they will be correctly recognized by Moodle.
a. The numerical value for the standardized selection point is ___ .
b. The numerical value for the truncation point is ___ seconds
c. The numerical value for the selection intensity is ___.
d. Calculate the selection differential. S =___ seconds.
e. The mean of the selected parents is ___ seconds.
f. The response to selection is ___ seconds.
g. The mean of the progeny generation is ___seconds.
