I just want someone to look over my answers to make sure I am calculating correctly. I am using the Hardy-Weinberg Equlibrium to figure out the answers to the questions. Thank you,
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 9.3 seconds with a standard deviation of 0.32 sec. You selected the fastest 10% of your current population to be parents of the next generation. The broad and narrow sense heritability values for racing speed in roaches are 0.93 and 0.78, 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. The numerical value for the standardized selection point is The numerical value for the truncation point is seconds. The numerical value for the selection intensity is Calculate the selection differential. S = seconds. The mean of the selected parents is seconds. The response to selection is seconds. The mean of the…
I am testing the prediction that spiders with colors that match a flower (cryptic coloration) will have greater success hunting bees visiting that flower. I set up two treatments for spiders: those matching their flower and those not matching their flower. I measure how long it takes each of them to catch a bee. What kind of statistical test would be best for testing my prediction? Chi-square ●ANOVA Regression

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 feet/second (ft/sec) with a standard deviation of 0.41 ft/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.

Data for two populations are shown below in Figs (a) and (b), respectively. The slopes of the best fit lines are 1 and 0.6, respectively. The corresponding correlation coefficients are 0.2 and 0.7, respectively. Which 3 of the following are true? O The heritability estimated in population (a) is 1 and in population (b) is 0.6. O The heritability estimated in fig (a) must be less than that of (b) because (a) has more variation (spread in the data around the best fit line) O The heritability estimated in population (a) is 0.3. O Although, the figures indicate that there is a heritability for both, the heritability estimates for both populations is not given. The heritability indicated within population (a) is greater than that indicated within population (b). O Population (a) has greater variation about the best fit line, implying that one's ability to predict offspring trait values based on their specific parents' trait value is greater in population (b) than in population (a).…
The following statements are either true or false. Indicate true or false and justify your answer briefly. An unbiased estimator is said to be consistent if the difference between the estimator and the population parameter grows smaller as the sample size grows larger. An unbiased estimator is a sample statistic whose expected value equals the population parameter. Knowing that an estimator is unbiased neither assures us that its expected value equals the population parameter, nor does it tell us how close the estimator is to the population parameter. A specific confidence interval obtained from sample data will always correctly estimate the population parameter.
A researcher counts the seeds produced by 100 wild plants growing on a roadside and finds the mean to be 55 and the variance to be 16. She then uses cuttings from one plant to produce clonal populations, which she then grows on a new roadside (in environmentally variable conditions). From this new clonal population she finds the mean to be 50 and the variance to be 2. What is the broad sense heritability? answer to two decimal places
